zookeeper中没有hbase的master

hbase出了一个错，

hbase(main):001:0> list
    TABLE

    ERROR: Can't get master address from ZooKeeper; znode data == null
    
    Here is some help for this command:
    List all tables in hbase. Optional regular expression parameter could
    be used to filter the output. Examples:
    
      hbase> list
      hbase> list 'abc.*'
      hbase> list 'ns:abc.*'
      hbase> list 'ns:.*'

看出错信息是不能从zookeeper中得到master地址。用hbase zkcli命令查看

[zk: xxxx:2181(CONNECTED) 0] ls /
    [hbase, zookeeper]
    [zk: xxxx:2181(CONNECTED) 1] ls /hbase
    [meta-region-server, backup-masters, table, draining, region-in-transition, table-lock, balancer, namespace, hbaseid, online-snapshot, replication, splitWAL, recovering-regions, rs]

确实没有master文件夹。然后我就关闭hbase和hadoop，清空zookeeper的data目录，在重启就好了。

[zk: xxxx:2181(CONNECTED) 0] 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]

出现了master文件夹。不知道是什么原因造成的，记录一下。
