Varun Vasudev commented on YARN-4913:
-------------------------------------

[~xgong] - couple of issues with the latest patch -
# Can you please change the help message for -out to "Local directory for storing individual container logs. The container logs will be stored based on the node the container ran on."
# When I give a bad location for the -out option, the command just prints an exception and hangs
