【Hbase】Master startup cannot progress, in holding-pattern until region onlined.

 

后台报错信息：

master.HMaster: hbase:meta,,1.1588230740 is NOT online; state={1588230740 state=OPEN,
ts=1543610616273, server=regionserver1.domain.com,41213,1543389145213}; ServerCrashProcedures=true.
Master startup cannot progress, in holding-pattern until region onlined


解决方案：
The workaround is to manually clean up the znode from ZooKeeper.

   从zk上手工清楚znode。

  connect to the cluster zookeeper instance and delete the following node before restart:

 /usr/hdp/current/zookeeper-client/bin/zkCli.sh -server localhost:2181
[zk: localhost:2181(CONNECTED) 0] rmr /ams-hbase-unsecure/meta-region-server

 

hbase就可以正常运行了。
