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

Question

我正在尝试设置 Hbase 的多节点集群。当我在 slave 上执行 jps 时，我得到了

5780 Jps
5558 HQuorumPeer
5684 HRegionServer
1963 DataNode
2093 TaskTracker

同样在 master 上我得到

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

一切都正常运行。但是当我尝试在 hbase shell 上创建表时。报错

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

我的奴隶的区域服务器日志(区域服务器正在运行):

仅供引用，我还处理了主机和从机上的/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 更改为 naresh-PC。但是仍然出现这个错误

Answer 1

尝试清除 Zookeeper 中的所有状态。

• 停止 Zookeeper
• 删除 Zookeeper 数据目录
• 启动动物园管理员

我遇到了同样的问题并遵循了这种方法并且效果很好。
