org.apache.hadoop.hbase.PleaseHoldException:主机正在初始化

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

5780 Jps
5558 HQuorumPeer
5684 HRegionServer
1963 DataNode
2093 TaskTracker

同样，在master上我得到了

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

EVerything运行正常。但是当我尝试在hbase shell上创建表时。它会给出一个错误

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

我的备机的regionserver日志( region server正在运行)：

仅供参考，我还处理了主服务器和从服务器上的/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。但是仍然得到这个错误

Answer 1

尝试清除Zookeeper中的所有状态。

• Stop Zookeeper
• Wipe Zookeeper data directory
• Start Zookeeper

我得到了同样的问题，并遵循这种方法，它工作得很好。

Answer 2

您需要将从节点上的配置更改为指向主节点。它当前指向localhost，而不是连接到实际的master：

localhost "org.apache.hadoop.hbase.ipc.HBaseClient$FailedServerException:此服务器在失败服务器列表中：

/127.0.0.1:60000，地址为"

Answer 3

我在Docker内部托管我自己的集群。以下是在我的案例中起作用的方法。我在HBase日志文件中查找错误，发现“主机传递给我们一个不同的主机名以供使用”

`[root@docker-iop bin]# grep ERROR /var/log/hbase/hbase-hbase-regionserver-bi-mgmt01.local.log
2016-10-06 00:05:29,816 ERROR [regionserver/bi-mgmt01.local/111.11.2.3:16020] regionserver.HRegionServer: Master passed us a different hostname to use; was=my-host-name, but now=111.22.33.444'

我将my-host-name映射到我的主机文件中的111.22.333.444，重新启动了HBase，它工作了。
