-----------------------------------------
[[email protected]] Thanks for your comment, and I did check this command
usage on debain as well as OS/X. And now tested in cygwin as well, it works
with double dash (--). Please suggest whether I need to modify the patch or not.
[~jayunit100] sure, will try to add test and resubmit the patch.

> In the environment where setsid available, kill command is constructed with
> single dash, which throws ExitCodeException (improper usage of command)
> {noformat}
> kill -signal_num -<process_group_id>
> {noformat}
> Encountered this issue due to YARN-3561
> Kill command need to be constructed with double dash (--) which means "end of
> command options" i.e. it tells ssh command not to try to parse what comes
> after command line options. It should be constructed as follows :
> {noformat}
> kill -signal_num -- -<process_group_id>
> {noformat}
