> This seems to have broken working scenarios with Hive MR.  We now see hadoop.tmp.dir is always set to /tmp/hadoop-hive (in job.xml). This creates problems on a multi-tenant hadoop cluster since ownership of tmp folder is set to the user who executes the jobs first and other users fails to write to tmp folder.
> E.g. User1 run job and /tmp/hadoop-hive is created on worker node with ownership to user1 and sibsequently user2 tries to run a job and job fails due to no write permission on /tmp/hadoop-hive/
> Old behavior allowed multiple tenants to write to their respective tmp folders which was secure and contention free. User1 - /tmp/hadoop-user1, User2 - /tmp/hadoop-user2.
