Hbase集群搭建

JDK版本和HBASE对应关系

HBase Version JDK 6 JDK 7 JDK 8
2 Not Supported Not Supported yes
1.3 Not Supported yes yes
1.2 Not Supported yes yes
1.1 Not Supported yes Running with JDK 8 will work but is not well tested.
1 Not Supported yes Running with JDK 8 will work but is not well tested.
0.98 yes yes Running with JDK 8 works but is not well tested. Building with JDK 8 would require removal of the deprecated remove() method of thePoolMap class and is under consideration. See HBASE-7608 for more information about JDK 8 support.
0.94 yes yes N/A

 

Hadoop和HBASE对应关系

 

HBase-0.94.x HBase-0.98.x
 (Support for Hadoop 1.1+ is eprecated.)
HBase-1.0.x (Hadoop 1.x is NOT supported) HBase-1.1.x HBase-1.2.x HBase-1.3.x
Hadoop-1.0.x X X X X X X
Hadoop-1.1.x S NT X X X X

Hadoop version support matrix
"S" = supported "X" = not supported "NT" = Not tested
我们这里选用的软件版本如下
Hadoop 2.7.1
Hbase hbase-1.2.4
jdk1.8.0_101
第一步,从apache基金会下载最新版本
https://mirrors.tuna.tsinghua.edu.cn/apache/hbase/1.2.4/hbase-1.2.4-bin.tar.gz

第二步,解压到服务器

tar -zxvf hbase-1.2.4
第三步,配置hbase集群,要修改3个文件(首先zk集群已经安装好了)
注意:由于hbase最终数据存放到hdfs,故需要把hadoop的hdfs-site.xml和core-site.xml 放到hbase/conf下
1.在master 上修改hbase-env.sh
export JAVA_HOME=/usr/java/jdk1.8.0_101
//告诉hbase使用外部的zk,如果使用内部的zk,设置为true(单机伪分布式)
export HBASE_MANAGES_ZK=false
# The maximum amount of heap to use. Default is left to JVM default.
export HBASE_HEAPSIZE=8G

2.修改hbase-site.xml

<configuration>
    <property>
            <name>hbase.rootdir</name>
            <value>hdfs://node1:9000/hbase</value>
    </property>
    <property>
            <name>hbase.cluster.distributed</name>
            <value>true</value>
    </property>
    <property>
            <name>hbase.zookeeper.quorum</name>
            <value>node1:2181,node2:2181,node3:2181</value>
    </property>
</configuration>

3.指定机器为regionserver,不单独指定master。其中:在哪个机器上启动,哪台就是master,在regionservers文件说明要启动的HRegionServer

vim regionservers
node1
node2
node3
node4

第四步,拷贝配置好的hbase文件到其他节点

第五步:

1.启动所有的hbase
     分别启动zk
          ./zkServer.sh start
     启动hdfs集群
          start-dfs.sh
     启动hbase,在主节点上运行:
          start-hbase.sh
6.通过浏览器访问hbase1.2.4版本管理页面
        node1:16010(于0.98 版本不同)
7.为保证集群的可靠性,要启动多个HMaster(可选)
        hbase-daemon.sh start master
