Subject [jira] [Commented] (HADOOP-9752) Latest Ubuntu (13.04) /bin/kill parameter for process group requires a 'double dash kill -0 -- -<pid>

    [ https://issues.apache.org/jira/browse/HADOOP-9752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13717893#comment-13717893

Jean-Baptiste Onofré commented on HADOOP-9752:
----------------------------------------------

Good catch Robert.

jbonofre@vostro:~$ /bin/kill -1 -34243
/bin/kill: invalid option -- '3'
...
jbonofre@vostro:~$ /bin/kill --version
kill from procps-ng 3.3.3

I checked with:
jbonofre@vostro:~$ which kill
/bin/kill

and the output confused me.

I gonna take a look on that to see if we can find a workaround that work with "all" kill commands.

>    Affects Versions: 3.0.0, 2.0.4-alpha
>            Reporter: Robert Parker

> This changed on Ubuntu 12.10 and later.  This prevents the kill command from executing
correctly in Shell.java.
> There is a bug filed in Ubuntu but there is not much activity. https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/1077796
