Ramki/John Many Thanks, that really helped. I have run the add jars in the new session and it appears to be running. However i was wondering about by passing MR, why would we do it and what is the use of it. Will appreciate any input. Thanks Sai

For the query, hive> select tweet_id from twitter limit 5; I think you need to add JSON jars to overcome this error. You might have added these in a previous session. If you want these jars available for all sessions, insert the add jar statements to your $HOME/.hiverc file. To bypass MapReduce set hive.exec.mode.local.auto = true; to suggest Hive to use local mode to execute the query. If it still uses MR, try set hive.fetch.task.conversion = more;. -Ramki.
