Robert Kanter commented on OOZIE-1770:
--------------------------------------
{quote}Interestingly, running a Container that doesn’t do much (e.g. a “Hello
World” Java action), runs so fast, that Oozie is now the bottleneck. The
callback comes in before the action has a chance to transition to RUNNING, so
Oozie complains. We fixed this by adding a delay. We’ll probably want to
improve this.{quote}
I believe this should be fixed by OOZIE-2126. It fixes this requeueing the
callback and retrying to "receive" it a few times to allow Oozie time to
transition the action.
