Jian He commented on YARN-1446:
-------------------------------

Add a new configuration for the poll interval.

fixed other comments also.

> When user kills an application, it should wait until the state store is done with saving the killed status of the application. Otherwise, if RM crashes in the middle between user killing the application and writing the status to the store, RM will relaunch this application after it restarts.
