Harsh J updated MAPREDUCE-2944:
-------------------------------
Attachment: MAPREDUCE-2944.patch
+1 on most recent patch. I just made some superficial changes (uploaded).
Committing.
Stuff I mainly changed was to remove newlines from exception messages. We
should never do that as it messes the logs and stuff that would look for
exceptions and stack traces. One long line of message is fine, lets always
follow that ahead :)
That + some doc message fixes to look a bit more clear.
> Improve checking of input for Api displayTasks()
