org.apache.hadoop.hbase.PleaseHoldException: Master 正在初始化 [英] org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

问题描述

我正在尝试设置 Hbase 的多节点集群.当我在奴隶上做 jps 时，我得到

I am trying to setup the multinode cluster of Hbase. When i do the jps on slave i get

5780 Jps
5558 HQuorumPeer
5684 HRegionServer
1963 DataNode
2093 TaskTracker

同样在主人身上我得到

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

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

EVerything is runnnig properly. But when i try to create table on hbase shell. It gives an error

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

我的从站的区域服务器日志(区域服务器正在运行的地方):

regionserver log of my slave(where region server is running):

仅供参考，我还处理了 master 和 slave 上的/etc/hosts 文件.

FYI, i have also took care of /etc/hosts file on both master and slave.

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.但是还是出现这个错误

I again did changes in /etc/hosts file 127.0.1.1 to naresh-PC. But still getting this error

推荐答案

尝试清除 Zookeeper 中的所有状态.

Try clearing all the states in Zookeeper.

• 停止 Zookeeper
• 擦除 Zookeeper 数据目录
• 启动 Zookeeper

我遇到了同样的问题，并采用了这种方法，效果很好.

I was getting the same issue and followed this approach and it worked fine.
