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,60000,1411261739960
Backup master addresses:
Region server holding hbase:meta: localhost,60020,1411261739301
Region servers:
 localhost,60020,1411261739301
/hbase/replication: 
/hbase/replication/peers: 
/hbase/replication/rs: 
/hbase/replication/rs/localhost,60020,1411261739301: 
Quorum Server Statistics:

四、zk_cli.sh


[zk: 192.168.230.128:2181(CONNECTED) 30] 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: 192.168.230.128:2181(CONNECTED) 31] ls /
[hbase, zookeeper]
[zk: 192.168.230.128:2181(CONNECTED) 32] ls /hbase

[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。
