Operation category READ is not supported in state standby at org.apache.hadoop.hdfs.server.namenode.ha.Standby

[Arthur Chan]

Hi,

I have HDFS HA with two namenodes (nn1 and nn2 respectively)


When the namenode nn1 is failover to nn2,  when querying HIVE, I got the
following error:

Query Failed: An Error Occurred

org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR:
