Hbase报错"org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.StandbyException): Operation ca"

Hbase报org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.StandbyException): Operation category READ is not supported in state standby错误

因为掉电,导致hadoop 的HA 出现 org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.ipc.StandbyException): Operation category READ is not supported in state standby 此问题,原来从web 页面查看,是两个节点都变成了standy,所以要切换  


hdfs haadmin -transitionToActive --forcemanual nn1 


再次访问http://localhost:50070/就变一active,一个standy
