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

 HBase is rooted at /hbase
 Active master address: localhost,,
 Backup master addresses:
 Region server holding hbase:meta: localhost,,
 Region servers:
  localhost,,
 /hbase/replication:
 /hbase/replication/peers:
 /hbase/replication/rs:
 /hbase/replication/rs/localhost,,:
 Quorum Server Statistics:
  192.168.230.128:

   Latency min/avg/max: //

四、zk_cli.sh

 [zk: 192.168.230.128:(CONNECTED) ] ls
 ZooKeeper -server host:port cmd args
         connect host:port
         get path [watch]
         ls path [watch]
         set path data [version]
         rmr path
         delquota [-n|-b] path
         quit
         printwatches on|off
         create [-s] [-e] path data acl
         stat path [watch]
         close
         ls2 path [watch]
         history
         listquota path
         setAcl path acl
         getAcl path
         sync path
         redo cmdno
         addauth scheme auth
         delete path [version]
         setquota -n|-b val path
 [zk: 192.168.230.128:(CONNECTED) ] ls /
 [hbase, zookeeper]
 [zk: 192.168.230.128:(CONNECTED) ] ls /hbase
 [meta-region-server, backup-masters, table, draining, region-in-transition, table-lock, running, master, namespace, hbaseid, online-snapshot, replication, splitWAL, recovering-regions, rs]
 [zk: 192.168.230.128:(CONNECTED) ]

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。
