> SSH action can be too fast for Oozie sometimes
> ----------------------------------------------

> Key: OOZIE-2126
> URL: https://issues.apache.org/jira/browse/OOZIE-2126
> Project: Oozie
> Issue Type: Bug

> Reporter: Robert Kanter

> We've seen a timing problem with the SSH action where the callback comes back
> too fast, before the action has transitioned to RUNNING and is still in PREP.
> This causes Oozie to ignore the callback, which means it won't find out that
> the action completed until it manually checks (default=10min). This happened
> in an HA setup, but I think it could happen even without HA. Adding a 30
> second delay into the ssh scripts fixed the problem, but ideally we should
> come up with a better solution.
> Here's the relevant logs:
