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:

四、zk_cli.sh
