Zhijie Shen commented on YARN-1716:
-----------------------------------
Writer lock is not necessary in tranistion classes, all the transition code is
already executed in the writer lock. See:
{code}
public void handle(RMContainerEvent event) {
{code}
> finishedStatus is accessed without proper locking in
> RMContainerImpl#FinishedTransition#transition()
> ----------------------------------------------------------------------------------------------------
