HBase与Zookeeper数据结构查询

一、前言

 　最近一年了吧，总是忙于特定项目的业务分析和顶层设计，很少花时间和精力放到具体的技术细节，感觉除了架构理念和分析能力的提升，在具体技术层次却并没有多大的进步。因为一些原因，总被人问及一些技术细节，很多细节都模糊了，花点时间，温习一下吧。技术部分将作为下一个阶段的工作重点。　

二、操作说明

查看Zookeeper内部HBase相关数据，有两个主要的渠道：一、通过Hbase shell命令zk_dump查看；二、通过zk_cli.sh查看；

三、zk_dump

 1 HBase is rooted at /hbase 2 Active master address: localhost,60000,1411261739960 3 Backup master addresses: 4 Region server holding hbase:meta: localhost,60020,1411261739301 5 Region servers: 6  localhost,60020,1411261739301 7 /hbase/replication:  8 /hbase/replication/peers:  9 /hbase/replication/rs: 10 /hbase/replication/rs/localhost,60020,1411261739301: 11 Quorum Server Statistics:12  192.168.230.128:218113   Zookeeper version: 3.4.6-1569965, built on 02/20/2014 09:09 GMT14   Clients:15    /192.168.230.128:54264[1](queued=0,recved=204,sent=212)16    /192.168.230.128:54269[1](queued=0,recved=113,sent=113)17    /192.168.230.128:54265[1](queued=0,recved=460,sent=507)18    /192.168.230.128:54271[1](queued=0,recved=131,sent=131)19    /192.168.230.128:54274[1](queued=0,recved=86,sent=86)20    /192.168.230.128:54656[1](queued=0,recved=12,sent=12)21    /192.168.230.128:54654[1](queued=0,recved=3,sent=3)22    /192.168.230.128:54270[1](queued=0,recved=94,sent=94)23    /192.168.230.128:54481[1](queued=0,recved=242,sent=242)24    /192.168.230.128:54657[0](queued=0,recved=1,sent=0)25   26   Latency min/avg/max: 0/1/15527   Received: 135228   Sent: 140629   Connections: 1030   Outstanding: 031   Zxid: 0x6532   Mode: standalone33   Node count: 38

四、zk_cli.sh

 1 [zk: 192.168.230.128:2181(CONNECTED) 30] ls 2 ZooKeeper -server host:port cmd args 3         connect host:port 4         get path [watch] 5         ls path [watch] 6         set path data [version] 7         rmr path 8         delquota [-n|-b] path 9         quit 10         printwatches on|off11         create [-s] [-e] path data acl12         stat path [watch]13         close 14         ls2 path [watch]15         history 16         listquota path17         setAcl path acl18         getAcl path19         sync path20         redo cmdno21         addauth scheme auth22         delete path [version]23         setquota -n|-b val path24 [zk: 192.168.230.128:2181(CONNECTED) 31] ls /25 [hbase, zookeeper]26 [zk: 192.168.230.128:2181(CONNECTED) 32] ls /hbase27 [meta-region-server, backup-masters, table, draining, region-in-transition, table-lock, running, master, namespace, hbaseid, online-snapshot, replication, splitWAL, recovering-regions, rs]28 [zk: 192.168.230.128:2181(CONNECTED) 33]

五、说明

　　关于输出结果的解读，就不去细说了，感兴趣的兄弟，自己去问度娘吧。
