Subject [jira] Commented: (HADOOP-1380) We should have a util.Subprocess class with utilities for starting subprocesses
Date Mon, 06 Aug 2007 20:27:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12518014

Owen O'Malley commented on HADOOP-1380:
---------------------------------------

Of course streaming would be fixed to use this. However, it would just kill the immediate
child. Any subprocesses that had forked off of the application, would be the applications
responsibility.

> I'd like a utility class for launching subprocesses. In particular, I want there to be
a list of launched subprocesses and when the jvm is shutdown, a hook will destroy all of the
subprocesses. Otherwise, when a task is killed, the subprocesses continue on.
