Subject [jira] [Commented] (HIVE-3969) Session state for hive server should be cleaned-up
Date Tue, 18 Mar 2014 17:07:45 GMT


Ashutosh Chauhan commented on HIVE-3969:

Although, HIVE-6364 is marked as duplicate, I don't think it is a duplicate. This one fixes
the problem of unloading registered jars, whereas HIVE-6364 talks about setting correct class
loader for HS2. So, it seems there are two independent problem, both of which needs to be
[~navis] Although, you raised the bug for HS1, I think same exact problem is also on HS2.
But, I think fix is in same area, so it doesn't really matter.  I think we should use sun.misc.ClassLoaderUtil
for now and than switch over to jdk7 in near future for a clean solution. Would  you like
to rebase this patch?
