>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6263
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: client

> 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.
