Devaraj K commented on MAPREDUCE-2925:
--------------------------------------
Thanks Vinod and Sharad for clarifying.
bq. Client should check if JobHistoryServer(JHS) is configured or not. To
facilitate this, we should not have a default address for JHS on the client. If
it is not configured, client should not attempt to reach JHS.
It is good idea. We can implement this.
bq. In ClientServiceDelegate, we need to unwrap the InvocationTargetException
to get the exception thrown by the method. If the wrapped exception is of type
YarnRemoteException, we should return from the call. (BTW, this is the real bug
you are running into and needs fixing). Otherwise it is a connection error and
we should just keep retrying.
I am also thinking exactly same for this case.
I will update the patch with these changes.
