Review request for Ning Zhang.
Summary
-------
Basically there is an additional place in Hive where a child JVM can be
started, that I wasn't aware of. I added to that place (MapRedLocalTask) update
of debug environment variables as it is being already done in MapRedTask.
By the way I added new debug option: swapSuspend, since I was very often using
hive --debug:mainSuspend=n,childSuspend=y whereas now --debug:swapSuspend will
be sufficient.
This addresses bug HIVE-2578.

Testing
-------
Tested on sample queries that it works (e.g. select s1.key, count(*) from src
s1 join src s2 on s1.key = s2.key group by s1.key, s2.value; )
Thanks,
Robert
