org.apache.hadoop.hbase.PleaseHoldException:Master正在初始化

Question

我正在尝试设置Hbase的多节点集群.当我做奴隶的jps我得到

5780 Jps
5558 HQuorumPeer
5684 HRegionServer
1963 DataNode
2093 TaskTracker

同样在主人身上我得到了

4254 SecondaryNameNode
15226 Jps
14982 HMaster
3907 NameNode
14921 HQuorumPeer
4340 JobTracker

一切都运行正常.但是当我尝试在hbase shell上创建表时.它给出了一个错误

ERROR: org.apache.hadoop.hbase.PleaseHoldException: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

我的slave的regionserver log(区域服务器正在运行):

仅供参考,我还在主服务器和从服务器上处理/ etc/hosts文件.

127.0.0.1       localhost
127.0.0.1       naresh-PC

我再次将/ etc/hosts文件127.0.1.1中的更改​​更改为naresh-PC.但仍然得到这个错误

Answer 1

尝试清除Zookeeper中的所有状态.

• 停止Zookeeper
• 擦除Zookeeper数据目录
• 重启它

我得到了同样的问题,并遵循这种方法,它工作得很好.
