-----------------------------------
Assuming the setSIDIsAvailable works on fedora/deb, it should work on all
systems.. right? [~ste...@apache.org]

> Project: Hadoop Common
> Issue Type: Bug
> Components: util
> Affects Versions: 2.6.0
> Environment: debian 7
> Reporter: Chackaravarthy
> Assignee: Chackaravarthy

> 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}
