We are trying to do hdfs replication from prod(CDH 5.x) to test(CDP 7.x) and getting a kerberos principal error:
Server has invalid Kerberos principal: hdfs/prodhostxx.com@TESTREALM, expecting: hdfs/prodhostxx.com@PRODREALM
Not sure why it is picking up TEST realm instead of the PROD realm in the job. The Peer test shows connected fine. Thanks!
