MENG DING updated YARN-1643:
----------------------------
Attachment: YARN-1643.2.patch
Attach patch for {{ContainersMonitorImpl}} for review.
Currently the {{ContainersMonitorImpl}} starts up one monitoring thread, and by
default checks started and stopped containers every 3 seconds.
For resized containers, we cannot use the same logic as the delay is
unacceptable.
A wait/notify mechanism is implemented such that as soon as a
{{CHANGE_MONITORING_CONTAINER_RESOURCE}} event is received, the monitor cycle
is immediately triggered.
> Make ContainersMonitor can support change monitoring size of an allocated
> container in NM side
