I have succesfully setup a hadoop cluster with HDFS HA enabled. I did a manual failover of Active NN (nn1) . Now the Standby NN (nn2) has become Active as expected. nn1 is now the standby. All HDFS write and read operations work fine (hdfs command line ..). However the below error pops up while using Hive (create table ) . I know turning the nn1 back to ACTIVE solves the issue. Looking for workarounds which doesn't require this manual operation. Thanks in advance.
