Jian He commented on YARN-1368:
-------------------------------

bq. should be container_reports
it's  a repeated field
bq. Better to use compareAndSet in a while loop in case of race condition
I changed to use synchronized keyword to make code easier.
bq. It's better to add a test for ContainerRecoveryReport
added.

> YARN-1367 adds support for the NM to tell the RM about all currently running containers
upon registration. The RM needs to send this information to the schedulers along with the
NODE_ADDED_EVENT so that the schedulers can recover the current allocation state of the cluster.
