1、使用create的时候无法创建成功。

2、查询zookeeper中的日志：

2021-05-14 19:01:07,650 [myid:2] - WARN  [NIOWorkerThread-19:[email protected]] - Unable to read additional data from client sessionid 0x200011aba2a0003, likely client has closed socket
2021-05-14 19:04:18,748 [myid:2] - INFO  [NIOWorkerThread-14:[email protected]] - Submitting global closeSession request for session 0x200011aba2a0004

           

3、查询hbase中的日志：

通过查看以上日志并不知道什么问题导致的

解决方式：

1、首先做好hbase数据的备份。

2、然后删除hdfs上面的hbase。

3、进入zkCli.sh 客户端，将hbase的节点删除掉。

4、重新启动hbase，问题解决。
