@mrizvi I didnt mean that. Its not compulsory for this operation. The api end point which I provided should grant the necessary role.

Please perform these two quick checks : 1) From ambari, go to hive service and check that the config changes you made are reflecting correctly. 2) Restart hive service. (You might need to restart oozie if cluster has this installed) After this try to run the update command. ... View more
