Priority: Blocker (was: Major)
> Fix race conditon in check() methods and rewrite check() logic
> --------------------------------------------------------------

> Key: OOZIE-2915
> URL: https://issues.apache.org/jira/browse/OOZIE-2915
> Project: Oozie
> Issue Type: Sub-task
> Reporter: Peter Bacsko
> Priority: Blocker
>
> There is a race condition inside {{MapReduceActionExecutor.check()}}.
> Comment from Rohini:
> bq. This code will have race condition issues. super.check() will check the
> status of launcher AM if action data file is not found. While it starts the
> check, if it completes then it will read the NEW_ID from action data and mark
> the action as completed even though the mapreduce job is just launched and is
> still running.
> Also the existing logic is convoluted and complex, hard to test. It should be
> refactored so we can validate the correctness of different code paths.
