Vinod Kumar Vavilapalli updated YARN-1661:
------------------------------------------
Attachment: YARN-1661.txt
The issue is that {{run()}} returns the value of success and the correct value
of _success_ is set right after that by {{finish()}} method of
ApplicationMaster.
Attaching patch that fixes this.
Tested that it works on a single node cluster.
> AppMaster logs says failing even if an application does succeed.
