[jira] [Created] (HADOOP-11989) Kill command for process group id throws ExitCodeException

Chackaravarthy created HADOOP-11989:
---------------------------------------

             Summary: Kill command for process group id throws ExitCodeException
                 Key: HADOOP-11989
                 URL: https://issues.apache.org/jira/browse/HADOOP-11989
             Project: Hadoop Common
          Issue Type: Bug
          Components: util
    Affects Versions: 2.6.0
         Environment: debian 7
            Reporter: 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}
