四、ZooKeeper Java客户端连接后的命令概述

键入help，可以看到有如下命令：

         connecthost:port
         getpath [watch]
         lspath [watch]
         setpath data [version]
         rmrpath
         delquota[-n|-b] path
         quit
         printwatcheson|off
         create[-s] [-e] path data acl
         statpath [watch]
         close
         ls2path [watch]
         history
         listquotapath
         setAclpath acl
         getAclpath
         syncpath
         redocmdno
         addauthscheme auth
         deletepath [version]
         setquota-n|-b val path

首先，看看列表命令，如下：

[zk: 127.0.0.1:2181(CONNECTED) 6] ls /
[zookeeper]

[zk: 127.0.0.1:2181(CONNECTED) 6] create/zk_test my_data
Created /zk_test

[zk: 127.0.0.1:2181(CONNECTED) 6] ls /
[zookeeper, zk_test]

下面，我们使用get命令来验证此znode节点相关的数据，如下：

[zk: 127.0.0.1:2181(CONNECTED) 7] get/zk_test
my_data
cZxid = 0x4
ctime = Fri May 02 08:28:40 UTC 2014
mZxid = 0x4
mtime = Fri May 02 08:28:40 UTC 2014
pZxid = 0x4
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 7
numChildren = 0

[zk: 127.0.0.1:2181(CONNECTED) 8] set/zk_test junk
cZxid = 0x4
ctime = Fri May 02 08:28:40 UTC 2014
mZxid = 0x5
mtime = Fri May 02 08:34:32 UTC 2014
pZxid = 0x4
cversion = 0
dataVersion = 1
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 4
numChildren = 0

[zk: 127.0.0.1:2181(CONNECTED) 10] delete/zk_test
[zk: 127.0.0.1:2181(CONNECTED) 11] ls /
[zookeeper]

[zk: 127.0.0.1:2181(CONNECTED) 12] quit
Quitting...
2014-05-02 08:49:47,415 [myid:] - INFO  [main:ZooKeeper@684] - Session:0x145bbdc9b460001 closed
