Cao Manh Dat commented on SOLR-13616:
-------------------------------------
I'm not sure we should change the {{waitForState}} logic to rethrow Exceptions
or revert back PrepRecoveryOp to its previous version (before SOLR-12801).
Need more thought about it.

> Based on some recent jenkins failures in TestPolicyCloud, I suspect there is
> a possible deadlock condition when attempting to delete a collection while
> recovery is in progress.
> I haven't been able to identify exactly where/why/how the problem occurs, but
> it does not appear to be a test specific problem, and seems like it could
> potentially affect anyone unlucky enough to issue poorly timed DELETE.
> Details to follow in comments...
