["Namit Jain (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12879002#action_12879002 ] 

Namit Jain commented on HIVE-543:
---------------------------------

Some minor comments:

1. Do you want to add a parameter for specifying the local directory ?
2. Not sure about the removal of synchronization around gWorkMap - let us go over it offline.
3. Need to see in more detail - why did the output change for only 2 join tests

> this is a little bit more than just mapred.job.tracker=local
> when run in this mode - multiple jobs are an issue since writing to same tmp directories is an issue. the following options:
> hadoop.tmp.dir
> mapred.local.dir
> need to be randomized (perhaps based on queryid).
