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:

   Zookeeper version: 3.4.-, built on // : GMT

   Clients:

    /192.168.230.128:[](queued=,recved=,sent=)

    /192.168.230.128:[](queued=,recved=,sent=)

    /192.168.230.128:[](queued=,recved=,sent=)

   Latency min/avg/max: //

   Received:

   Connections:

   Zxid: 0x65

   Mode: standalone

   Node count:

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。
