org.apache.hadoop.security.UserGroupInformation - PriviledgedActionException as:user_name(auth:KERBEROS) cause:javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]
I have also initiated crontab which does kinit by using the same keytab for every 1 hour but still am getting the same error and job fails to complete
