Sangjin Lee updated YARN-2183:
------------------------------
Attachment: YARN-2183-trunk-v7.patch
v.7 patch posted. I switched to using 2 threads for the executor service, and
simplified the race condition handling. Also, switched from AtomicBoolean to
Lock as it's conceptually clearer and behavior-wise identical.
For the overall diff, see

For v.6 -> v.7, see
