I expect us to start cutting the branch for 0.4 in the next 2-3 weeks. Once we move our internal systems to the head of the trunk we can safely cut a branch out.

There is currently no way to get Hive version from the command line. I will leave the other 2 questions to Ashish and Joydeep.

BTW, is there a quick way to find out current hive version on command line like 'hive -v'? That would be helpful. Also, when would 0.40 be released? And would it work with 0.20.x w/o a patch? Thanks for the info! Eva. On 6/14/09 6:21 PM, "Zheng Shao" <[email protected]<http://[email protected]>> wrote: Hi Eva, Which version of Hive are you using? Is it Hive 0.3.0 release or Hive trunk? This bug is recently fixed in https://issues.apache.org/jira/browse/HIVE-495 It's not back-ported to Hive 0.3.0. I would suggest you to try hive svn trunk (I think it's time to make Hive 0.4.0 release from trunk soon).
