Owen O'Malley updated HADOOP-1380:
----------------------------------
Status: Open (was: Patch Available)
Brice,
Thanks for taking this on! It should probably include a call to it from
streaming and/or pipes so that we aren't adding uncalled code.
The SubProcessManager looks like a singleton, but the get method returns a new
instance each time. Shouldn't it cache it in a static variable?
In general, InterruptedExceptions should end the thread. Otherwise it is
impossible to tell them to stop.
> We should have a util.Subprocess class with utilities for starting
> subprocesses

> 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.
