Thanks Ted for your response
We have Hive 0.10 installed on CDH-4.2.0 hosted on UNIX environment. I am able to query and run DDL on Hive through both Hue interface and command line from UNIX box. So I am sure Hive is not going down.
Issue we are facing is with connecting to Hive through Tableau trial edition on my desktop.
We have tried connecting through both Windows XP and windows 7.
Any pointer would be helpful
