> I ran an MR2 application that would have been long running, and killed it
> programmatically using a YarnClient. The app was killed, but the client hung
> forever. The message that I saw, which spammed the logs, was "Watiting for
> application application_1389036507624_0018 to be killed."
> The RM log indicated that the app had indeed transitioned from RUNNING to
> KILLED, but for some reason future responses to the RPC to kill the
> application did not indicate that the app had been terminated.
> I tracked this down to YarnClientImpl.java, and though I was unable to
> reproduce the bug, I wrote a patch to introduce a bound on the number of
> times that YarnClientImpl retries the RPC before giving up.
