[jira] Created: (HADOOP-1380) We should have a util.Subprocess
class with utilities for starting subprocesses
We should have a util.Subprocess class with utilities for starting subprocesses
-------------------------------------------------------------------------------
Key: HADOOP-1380
URL: https://issues.apache.org/jira/browse/HADOOP-1380
Project: Hadoop
Issue Type: New Feature
Components: util
Affects Versions: 0.12.3
Reporter: Owen O'Malley
Assigned To: Owen O'Malley
Fix For: 0.14.0
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.

---------------------------------------
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.

---------------------------------------
By extension, is there a way to modify streaming to take advantage of this? We have a problem with streaming littering orphaned processes that we need fixed. Is it OK to attach that to this bug, or should I open a new JIRA?
