Hbase 出现 org.apache.hadoop.hbase.ipc.ServerNotRunningYetException: Server is not running yet 错误

1. 错误描述

ERROR: org.apache.hadoop.hbase.ipc.ServerNotRunningYetException: Server is not running yet

2. 解决方法

出现上面问题的原因是 hadoop的hdfs集群处在安全模式，解决问题方式就是手动退出安全模式.

hadoop dfsadmin -safemode leave

然后再重启hbase集群即可。
