> YARNRunner connects to the AM to send the kill job command then waits a
> hardcoded 10 seconds for the job to enter a terminal state. If the job fails
> to enter a terminal state in that time then YARNRunner will tell YARN to kill
> the application forcefully. The latter type of kill usually results in no
> job history, since the AM process is killed forcefully.
> Ten seconds can be too short for large jobs in a large cluster, as it takes
> time to connect to all the nodemanagers, process the state machine events,
> and copy a large jhist file. The timeout should be more lenient or
> configurable.
