> 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}
