--------------------------------

             Summary: When default container executor fails right away, at the CLI launching
our App Master, Client doesn't always get the signal to kill the job
                 Key: YARN-477
                 URL: https://issues.apache.org/jira/browse/YARN-477
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Eli Reisman


I have been porting Giraph to YARN (GIRAPH-13 is the issue) and when I launch my App Master,
if the container command line runs it successfully, any failure in the App Master or my launched
Giraph Tasks promptly reports to Client and ends my job run. However, if the command line
sent to the app master container fails to launch it at all, the error exit code is not propagating.
My client hangs with the job at containersUsed == 1 and state == ACCEPTED for as long as you
want to sit and wait before CTRL-C'ing your way out.

Disclaimer: this could be my fault. But I wanted to throw it out there in case its not. I
also (when this happens) not getting error logs since the app master never launched, so I
really have no visibility into why it failed to launch. I am sure its not launching, but the
client IS sending the app request, getting a container for my AM, and I see the command line
run on the container in my logs. Thats all.

Thanks! If this is a dup or "won't fix" for some reason, let me know and sorry for wasting
your time!
