Andras Piros commented on OOZIE-3009:
-------------------------------------

Root cause is following:
* there are (at least following) five test classes that are at the moment 
retrying the database operations for an extended time period, but they 
shouldn't (since these {{FaultInjection}} facility):
** {{TestBundleJobsDeleteJPAExecutor}}
** {{TestCoordJobsDeleteJPAExecutor}}
** {{TestPurgeService}}
** {{TestPurgeXCommand}}
** {{TestWorkflowJobsDeleteJPAExecutor}}
* as a consequence, these tend to timeout often
* when that happens, all the other modules are skipped because of the timeout
* the test cases of the skipped modules are not rerun on the second run

We need to extend {{PersistenceExceptionSubclassFilterRetryPredicate}} by 
following:
* if the {{Throwable}} does not have a root cause, and is either a 
{{RuntimeException}} (in case of {{FaultInjection}}), or a 
{{JPAExecutorException}} (e.g. {{Query.getResultList()}} returned an empty 
{{List}}), the predicate returns {{false}}
* for all the other cases the existing behavior kicks in

> Number of Oozie tests executed dropped after OOZIE-2854
