Robert Kanter commented on OOZIE-1906:
--------------------------------------
I looked into this more, and you are supposed to setup a Reaper to clean up old
lock parent znodes. Specifically, I think we can create a ChildReaper to look
at the location where we store all of the locks and it will take care of this
for us. Also, we only need to have one Oozie server running this.
