This is tricky to debug. Check logs of node and resource manager of YARN to see if you can trace the error. In the past I have to closely look at arguments getting passed to YARN container (they get logged before attempting to launch containers). If I still don't get a clue, I had to check the script generated by YARN to execute the container and even run manually to trace at what line the error has occurred.
BTW are you submitting the job from windows? On Thu, Feb 12, 2015, 3:34 PM Anders Arpteg <[email protected]> wrote: > Interesting to hear that it works for you.
