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

David Yan commented on HADOOP-9752:
-----------------------------------

The patch works for me on Ubuntu 13.04.  I successfully issued a kill request that actually
kills the application.  This is a very trivial change, so it would be nice if we could get
it in the next release if it's verified to work on other linux versions.

> 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
