zookeeper cli 如何创建一个空节点？

Question

创建命令：

create [-s] [-e] path data

创建节点时未指定数据字段。可以使用 ZooInspector

Answer 1

我使用了以下命令：create /test ""。

在 zkCli 结果上获取命令：

[zk: localhost:2181(CONNECTED) 14] get /test

cZxid = 0x4
ctime = Fri Sep 07 09:38:31 IRDT 2018
mZxid = 0x4
mtime = Fri Sep 07 09:38:31 IRDT 2018
pZxid = 0x4
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 0

最后，我下载了 zooInspector 来检查它是如何工作的，我创建了两个 znode：fromcli 和 fromInspector。因此，结果如下：

[zk: localhost:2181(CONNECTED) 20] ls /
[fromInspector, zookeeper, fromcli]
[zk: localhost:2181(CONNECTED) 21] get /fromcli

cZxid = 0x23
ctime = Fri Sep 07 11:11:39 IRDT 2018
mZxid = 0x23
mtime = Fri Sep 07 11:11:39 IRDT 2018
pZxid = 0x23
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 0
[zk: localhost:2181(CONNECTED) 22] get /fromInspector

cZxid = 0x24
ctime = Fri Sep 07 11:12:01 IRDT 2018
mZxid = 0x24
mtime = Fri Sep 07 11:12:01 IRDT 2018
pZxid = 0x24
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 0
