    [ https://issues.apache.org/jira/browse/HIVE-382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12694402#action_12694402

Raghotham Murthy commented on HIVE-382:
---------------------------------------

a few things:

1. Its not very apparently what kind of memory savings result with this change. is there a
way to add a test for that? 
2. do you need the clear() call at the end of the loop?
3. can you change warn to debug or info?
