Oozie4.2.0配置安装实战

软件版本号:

Oozie4.2.0。Hadoop2.6.0,Spark1.4.1。Hive0.14。Pig0.15.0。Maven3.2。JDK1.7,zookeeper3.4.6。HBase1.1.2,MySQL5.6

集群部署:

node1~4.centos.com     node1~4      192.168.0.31~34          1G*4 内存    1核*4 虚拟机

node1:NameNode 、ResourceManager;

node2:SecondaryNameNode、Master、HMaster、HistoryServer、JobHistoryServer

node3:oozie-server(tomcat)、DataNode、NodeManager、HRegionServer、Worker、QuorumPeerMain

node4:DataNode、NodeManager、HRegionServer、Worker、Pig client、Hive Client、HiveServer2、QuorumPeerMain、mysql

1. 编译Oozie4.2.0

此篇參考 http://oozie.apache.org/docs/4.2.0/DG_QuickStart.html#Building_Oozie 、 http://blog.csdn.net/u014729236/article/details/47188631 

1.1 编译环境准备

使用tomcat7,而不是tomcat6的下载地址:
1)下载压缩包oozie-4.2.0.tar.gz,并解压缩到/usr/local/oozie文件夹
2)改动pom.xml
/usr/local/oozie/oozie-4.2.0/distro/pom.xml
<get src=http://www.mamicode.com/"http://archive.apache.org/dist/tomcat/tomcat-6 ==>
<get src=http://www.mamicode.com/"http://archive.apache.org/dist/tomcat/tomcat-7

3) 改动maven setting.xml 。使用开源中国的库
<mirror>
      <id>nexus-osc</id>
      <name>OSChina Central</name>                                                                             
      <url>http://maven.oschina.net/content/groups/public/</url>
      <mirrorOf>*</mirrorOf>
</mirror>

1.2 编译

进入oozie解压缩文件夹,使用以下的命令:
bin/mkdistro.sh -DskipTests -Phadoop-2 -Dhadoop.auth.version=2.6.0 -Ddistcp.version=2.6.0 -Dspark.version=1.4.1 -Dpig.version=0.15.0 -Dtomcat.version=7.0.52 
假设增加了hbase或者hive。而且指定到较高版本号,则会出错,如:
#bin/mkdistro.sh -DskipTests -Phadoop-2 -Dhadoop.auth.version=2.6.0 -Ddistcp.version=2.6.0 -Dspark.version=1.4.1 -Dpig.version=0.15.0 -Dtomcat.version=7.0.52 #-Dhive.version=0.14.0 -Dhbase.version=1.1.2 ## 指定hive和hbase到较高版本号编译通只是

1.3 改动HDFS配置:

 改动hadoop core-site.xml,内容例如以下:
<property>
    <name>hadoop.proxyuser.[USER].hosts</name>
    <value>*</value>
  </property>
  <property>
    <name>hadoop.proxyuser.[USER].groups</name>
    <value>*</value>
  </property>
当中,[USER]须要改为后面启动oozie tomcat的用户
不重新启动hadoop集群,而使配置生效
hdfs dfsadmin -refreshSuperUserGroupsConfiguration
  yarn rmadmin -refreshSuperUserGroupsConfiguration
  

1.4 配置Oozie

(因为是在node3上部署oozie,所以把以下的压缩包复制到node3上)

1) 取得压缩包:
oozie-4.2.0/distro/target/oozie-4.2.0-distro.tar.gz
2) 解压缩:
tar -zxf oozie-4.2.0-distro.tar.gz

3)在oozie-4.2.0文件夹下新建libext文件夹。并把
ext-2.2.zip 复制到该文件夹下。
并拷贝hadoop相关jar包到该文件夹下
cp $HADOOP_HOME/share/hadoop/*/*.jar libext/
cp $HADOOP_HOME/share/hadoop/*/lib/*.jar libext/

把hadoop与tomcat冲突jar包去掉
mv servlet-api-2.5.jar servlet-api-2.5.jar.bak
mv jsp-api-2.1.jar jsp-api-2.1.jar.bak
mv jasper-compiler-5.5.23.jar jasper-compiler-5.5.23.jar.bak
mv jasper-runtime-5.5.23.jar jasper-runtime-5.5.23.jar.bak

拷贝mysql驱动到该文件夹下(使用mysql数据库,默认是derby)
scp mysql-connector-java-5.1.25-bin.jar node3:/usr/oozie/oozie-4.2.0/libext/

4)配置数据库连接,文件是conf/oozie-site.xml
<property>
    <name>oozie.service.JPAService.create.db.schema</name>
    <value>true</value>
</property>
<property>
    <name>oozie.service.JPAService.jdbc.driver</name>
    <value>com.mysql.jdbc.Driver</value>
</property>
<property>
    <name>oozie.service.JPAService.jdbc.url</name>
    <value>jdbc:mysql://node4:3306/oozie?

createDatabaseIfNotExist=true</value> </property> <property> <name>oozie.service.JPAService.jdbc.username</name> <value>root</value> </property> <property> <name>oozie.service.JPAService.jdbc.password</name> <value>root</value> </property> <property> <name>oozie.service.HadoopAccessorService.hadoop.configurations</name> <value>*=/usr/hadoop/hadoop-2.6.0/etc/hadoop</value> </property>



最后一个配置,是须要配置的,不然后面执行调度的时候,任务会报File /user/root/share/lib does not exist 的错误


5)启动前的初始化
a. 打war包  
bin/oozie-setup.sh prepare-war

b. 初始化数据库
bin/ooziedb.sh create -sqlfile oozie.sql -run


c. 改动oozie-4.2.0/oozie-server/conf/server.xml文件。凝视掉以下的记录
<!--<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />-->

d. 上传jar包
bin/oozie-setup.sh sharelib create -fs hdfs://node1:8020 

1.5 启动

bin/oozied.sh start

技术分享

2. 流程实例

数据为:bank.csv ,并已经上传到hdfs://node1:8020/user/root/bank.csv ,能够在http://zeppelin-project.org/docs/tutorial/tutorial.html页面下载该数据
(当执行Hive、Pig任务的时候须要把第一行数据删除)
默认全部操作用户都是root,假设是其它用户,可能须要改动相应的文件夹
配置环境变量:export OOZIE_URL=http://node3:11000/oozie

2.1 MR任务流程

1. job.properties :
oozie.wf.application.path=hdfs://node1:8020/user/root/workflow/mr_demo/wf
#Hadoop"R
jobTracker=node1:8032
#Hadoop"fs.default.name
nameNode=hdfs://node1:8020/
#Hadoop"mapred.queue.name
queueName=default

2. workflow.xml
<workflow-app xmlns="uri:oozie:workflow:0.2" name="map-reduce-wf">
    <start to="mr-node"/>
    <action name="mr-node">
        <map-reduce>
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <prepare>
                <delete path="${nameNode}/user/${wf:user()}/workflow/mr_demo/output"/>
            </prepare>
            <configuration>
                <property>
                    <name>mapred.job.queue.name</name>
                    <value>${queueName}</value>
                </property>
                <property>
                    <name>mapreduce.mapper.class</name>
                    <value>org.apache.hadoop.examples.WordCount$TokenizerMapper</value>
                </property>
                <property>
                    <name>mapreduce.reducer.class</name>
                    <value>org.apache.hadoop.examples.WordCount$IntSumReducer</value>
                </property>
                <property>
                    <name>mapred.map.tasks</name>
                    <value>1</value>
                </property>
                <property>
                    <name>mapred.input.dir</name>
                    <value>/user/${wf:user()}/bank.csv</value>
                </property>
                <property>
                    <name>mapred.output.dir</name>
                    <value>/user/${wf:user()}/workflow/mr_demo/output</value>
                </property>
            </configuration>
        </map-reduce>
        <ok to="end"/>
        <error to="fail"/>
    </action>
    <kill name="fail">
        <message>Map/Reduce failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <end name="end"/>
</workflow-app>

3. 执行:
1)拷贝workflow.xml文件到HDFS的 hdfs://node1:8020/user/root/workflow/mr_demo/wf/workflow.xml 文件夹;
2)在node3(node3既作为oozie的server也作为client)上执行 bin/oozie job -config job.properties -run ,就可以提交任务,提交任务后会返回一个jobId ,比如:
0000004-160123180442501-oozie-root-W
3) 使用 bin/oozie job -info 0000004-160123180442501-oozie-root-W 就可以查看流程状态;
4) 流程结束后。查看流程状态以及在相应的文件夹就可以查看输出结果。

2.2 Pig任务流程

1. job.properties
oozie.wf.application.path=hdfs://node1:8020/user/root/workflow/pig_demo/wf
oozie.use.system.libpath=true #pig流程必须配置此选项
#Hadoop"ResourceManager
resourceManager=node1:8032
#Hadoop"fs.default.name
nameNode=hdfs://node1:8020/
#Hadoop"mapred.queue.name
queueName=default

2.  workflow.xml
<workflow-app xmlns="uri:oozie:workflow:0.2"
name="whitehouse-workflow">
<start to="transform_job"/>
	<action name="transform_job">
		<pig>
			<job-tracker>${resourceManager}</job-tracker>
			<name-node>${nameNode}</name-node>
			<prepare>
				<delete path="/user/root/workflow/pig_demo/output"/>
			</prepare>
			<script>transform_job.pig</script>
		</pig>
		<ok to="end"/>
		<error to="fail"/>
	</action>
	<kill name="fail">
		<message>Job failed, error
			message[${wf:errorMessage(wf:lastErrorNode())}]
		</message>
	</kill>
	<end name="end"/>
</workflow-app>

3 . transform_job.pig pig任务用到的脚本
bank_data= http://www.mamicode.com/LOAD ‘/user/root/bank.csv‘ USING PigStorage(‘;‘) AS>4. 执行
1) 把 transform_job.pig ,workflow.xml 文件复制到 hdfs://node1:8020/user/root/workflow/pig_demo/wf/ 文件夹以下
2) 执行 bin/oozie job -config job.properties -run 
3) 执行 bin/oozie job -info jobId 查看相应任务的进度状态。或者在浏览器中的node3:11000 URL中查看全部任务;

2.3 Hive任务流程

注意:hive 任务执行完毕后,bank.csv文件会被删除(应该是移动到hive的warehouse文件夹下)。所以进行其它或者再次执行时须要又一次上传文件
1. job.properties
nameNode=hdfs://node1:8020
jobTracker=node1:8032
queueName=default
maxAge=30
input=/user/root/bank.csv
output=/user/root/workflow/hive_demo/output
oozie.use.system.libpath=true

oozie.wf.application.path=${nameNode}/user/${user.name}/workflow/hive_demo/wf
2. workflow.xml
<workflow-app xmlns="uri:oozie:workflow:0.2" name="hive-wf">
    <start to="hive-node"/>

    <action name="hive-node">
        <hive xmlns="uri:oozie:hive-action:0.2">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <prepare>
                <delete path="${output}/hive"/>
                <mkdir path="${output}"/>
            </prepare>
            <configuration>
                <property>
                    <name>mapred.job.queue.name</name>
                    <value>${queueName}</value>
                </property>
            </configuration>
            <script>script.hive</script>
            <param>INPUT=${input}</param>
            <param>OUTPUT=${output}/hive</param>
       		<param>maxAge=${maxAge}</param>
	 </hive>
        <ok to="end"/>
        <error to="fail"/>
    </action>

    <kill name="fail">
        <message>Hive failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <end name="end"/>
</workflow-app>
3. hive任务用到的脚本 script.hive
DROP TABLE IF EXISTS bank;

CREATE TABLE bank(
	age int,
	job string,
	marital string,education string,
 default string,balance int,housing string,loan string,
contact string,day int,month string,duration int,campaign int,
pdays int,previous int,poutcom string,y string
) 
 ROW FORMAT DELIMITED FIELDS TERMINATED BY ‘\073‘
 STORED AS TEXTFILE;

 LOAD DATA INPATH ‘${INPUT}‘ INTO TABLE bank;

INSERT OVERWRITE DIRECTORY ‘${OUTPUT}‘ SELECT * FROM bank where age > ‘${maxAge}‘;
注意:‘\073’ 代表分号;
4. 执行,參考上面


2.4 Hive 2 任务流程

1. job.properties 
nameNode=hdfs://node1:8020
jobTracker=node1:8032
queueName=default
jdbcURL=jdbc:hive2://node4:10000/default # hiveserver2 时,配置此选项
maxAge=30
input=/user/root/bank.csv
output=/user/root/workflow/hive2_demo/output
oozie.use.system.libpath=true

oozie.wf.application.path=${nameNode}/user/${user.name}/workflow/hive2_demo/wf

2. workflow.xml 
<workflow-app xmlns="uri:oozie:workflow:0.5" name="hive2-wf">
    <start to="hive2-node"/>

    <action name="hive2-node">
        <hive2 xmlns="uri:oozie:hive2-action:0.1">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <prepare>
                <delete path="${output}/hive"/>
                <mkdir path="${output}"/>
            </prepare>
            <configuration>
                <property>
                    <name>mapred.job.queue.name</name>
                    <value>${queueName}</value>
                </property>
            </configuration>

	    <jdbc-url>${jdbcURL}</jdbc-url>
            <script>script2.hive</script>
            <param>INPUT=${input}</param>
            <param>OUTPUT=${output}/hive</param>
       		<param>maxAge=${maxAge}</param>
	 </hive2>
        <ok to="end"/>
        <error to="fail"/>
    </action>

    <kill name="fail">
        <message>Hive2 failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <end name="end"/>
</workflow-app>
3. hive2用到的脚本: script2.hive
DROP TABLE IF EXISTS bank2;

CREATE TABLE bank2(
	age int,
	job string,
	marital string,education string,
 default string,balance int,housing string,loan string,
contact string,day int,month string,duration int,campaign int,
pdays int,previous int,poutcom string,y string
) 
 ROW FORMAT DELIMITED FIELDS TERMINATED BY ‘\073‘
 STORED AS TEXTFILE;

 LOAD DATA INPATH ‘${INPUT}‘ INTO TABLE bank2;

INSERT OVERWRITE DIRECTORY ‘${OUTPUT}‘ SELECT * FROM bank2 where age > ‘${maxAge}‘;

4. 执行,參考上面

2.5 Spark 任务流程

1. job.properties :
nameNode=hdfs://node1:8020
jobTracker=node1:8032
#master=spark://node2:7077 
master=spark://node2:6066
sparkMode=cluster
queueName=default
oozie.use.system.libpath=true
input=/user/root/bank.csv
output=/user/root/workflow/spark_demo/output
# the jar file must be local
jarPath=${nameNode}/user/root/workflow/spark_demo/lib/oozie-examples.jar
oozie.wf.application.path=${nameNode}/user/${user.name}/workflow/spark_demo/wf
因为sparkMode採用cluster,所以master的链接须要是以下的6066,:
技术分享
sparkMode使用client没有试验成功;

2. workflow.xml
<workflow-app xmlns=‘uri:oozie:workflow:0.5‘ name=‘SparkFileCopy‘>
    <start to=‘spark-node‘ />

    <action name=‘spark-node‘>
        <spark xmlns="uri:oozie:spark-action:0.1">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <prepare>
                <delete path="${output}"/>
            </prepare>
            <master>${master}</master>
        <mode>${sparkMode}</mode>   
            <name>Spark-FileCopy</name>
	 <class>org.apache.oozie.example.SparkFileCopy</class>
            <jar>${jarPath}</jar>
            <arg>${input}</arg>
            <arg>${output}</arg>
        </spark>
        <ok to="end" />
        <error to="fail" />
    </action>

    <kill name="fail">
        <message>Workflow failed, error
            message[${wf:errorMessage(wf:lastErrorNode())}]
        </message>
    </kill>
    <end name=‘end‘ />
</workflow-app>

3. 执行:
1) 这里用到的oozie-examples.jar 是在oozie-examples.tar.gz解压后的examples/apps/spark/lib文件夹以下
2) 上传oozie-examples.jar 到hdfs://node1:8020/user/root/workflow/spark_demo/lib/oozie-examples.jar 文件夹;上传workflow.xml到hdfs://node1:8020/user/root/workflow/spark_demo/wf/workflow.xml文件。
3) bin/oozie job -config job.properties -run 就可以执行;

4. 相关问题:
1) 这样的方式提交任务是通过yarn开启任务,然后提交到spark集群执行的。并非直接由spark集群执行的。例如以下图:
首先在8088 界面看到yarn开启的任务:
技术分享
接着去spark监控界面。相同能够看到监控界面:
技术分享

可是这样时间就不正确了,看日志:
技术分享
能够看到连接到了yarn的resourcemanager后。直接就连接了spark的master了,然后提交了任务,接着就直接yarn的任务就successed了,然后yarn就返回了。
查看spark的日志。时间也是吻合的:
技术分享
最后保存文件,关闭driver:技术分享

2.6  spark on yarn任务流程

參考官网的提示:
技术分享

1. job.properties:
nameNode=hdfs://node1:8020
jobTracker=node1:8032
#master=spark://node2:7077
#master=spark://node2:6066
master=yarn-cluster
#sparkMode=cluster
queueName=default
oozie.use.system.libpath=true
input=/user/root/bank.csv
output=/user/root/workflow/sparkonyarn_demo/output

jarPath=${nameNode}/user/root/workflow/sparkonyarn_demo/lib/oozie-examples.jar
oozie.wf.application.path=${nameNode}/user/${user.name}/workflow/sparkonyarn_demo
2. workflow.xml:
<workflow-app xmlns=‘uri:oozie:workflow:0.5‘ name=‘SparkFileCopy_on_yarn‘>
    <start to=‘spark-node‘ />

    <action name=‘spark-node‘>
        <spark xmlns="uri:oozie:spark-action:0.1">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <prepare>
                <delete path="${output}"/>
            </prepare>
            <master>${master}</master>
            <name>Spark-FileCopy-on-yarn</name>
	 <class>org.apache.oozie.example.SparkFileCopy</class>
            <jar>${jarPath}</jar>
            <spark-opts>--conf spark.yarn.historyServer.address=http://node2:18080 --conf spark.eventLog.dir=hdfs://node1:8020/spark-log --conf spark.eventLog.enabled=true</spark-opts>
		<arg>${input}</arg>
            <arg>${output}</arg>
        </spark>
        <ok to="end" />
        <error to="fail" />
    </action>

    <kill name="fail">
        <message>Workflow failed, error
            message[${wf:errorMessage(wf:lastErrorNode())}]
        </message>
    </kill>
    <end name=‘end‘ />
</workflow-app>

3. 执行;
1)环境准备:拷贝workflow.xml 到hdfs;//node1:8020/user/root/workflow/sparkonyarn_demo/workflow.xml文件
2)拷贝oozie-exmaples.jar 到 hdfs;//node1:8020/user/root/workflow/sparkonyarn_demo/lib/oozie-examples.jar文件
3)拷贝$SPARK_HOME/lib/spark-assembly-1.4.1-hadoop2.6.0.jar文件到hdfs;//node1:8020/user/root/workflow/sparkonyarn_demo/lib/spark-assembly-1.4.1-hadoop2.6.0.jar 
4) bin/oozie job -config job.properties -run 
5) 查看任务状态:
技术分享

4. 相关问题

1) spark 提交和spark on yarn 方式的差别:
spark on yarn也是使用yarn来提交任务,可是没有spark的任务,全部在yarn上执行,看日志的差别:
在8088的差别:
技术分享
技术分享
0000003-160123180442501-oozie-root-W任务前后仅仅有一个,而且有一个spark的任务(node2:8080),对比时间
spark on yarn的方式
技术分享
看到0000009-160123180442501-oozie-root-W 这个任务事实上是有两个yarn的任务组成的

查看oozie的日志监控:
技术分享
所以spark 的方式是yarn启动任务,然后由spark集群执行任务。然后结束;中间须要spark集群启动(也须要yarn集群启动)
而spark on yarn的方式则是yarn启动任务A ,然后在任务中调用另外一个yarn任务B。当任务B完毕后。再返回到任务A,最后任务A结束。中间不须要spark集群启动(这个看下图就知道了)

分享。成长,快乐

脚踏实地,专注
