John Thomason updated MAPREDUCE-7160:
-------------------------------------
Description:
If a YarnRuntimeException occurs during shutDownJob (in this case, at the line
'MRAppMaster.this.stop();') in MRAppMaster.java, the try/catch block will catch
it but the 'finally' block will not get executed. Additionally, the client
service should be stopped if an exception occurs and is not currently.
For example, if this error occurs:
{code:java}

Then the line

This means that the job end notification is not sent despite
[https://jira.apache.org/jira/browse/MAPREDUCE-6895?attachmentOrder=desc].
Additionally, this finally block should also call 'clientService.stop();', as
otherwise the following errors occur on the client side:
