Bikas Saha commented on YARN-422:
---------------------------------
Please be careful about callbacks wrt thread being used and also potential
locking order/deadlocks. As an example, in AMRMClient, we used different
threads for actual RPC work and callback. There was a consumer producer pattern
between the 2 threads using a blocking thread safe queue. The callback thread
did not hold any locks when calling back up to the client.
