Ajay Yadava commented on FALCON-1598:
-------------------------------------
I am guessing the problem is it passes the check that the feed exists and then
proceeds to delete it and other requests deletes it first. This causes it to
fail with an exception. That said I totally agree that the test itself
shouldn't fail. If a test fails arbitrarily then it looses it's usefulness. If
it's too difficult to fix the test then we should probably delete the test.

> Looking at the code, I found that the test expects one of the two delete
> commands to fail when attempting to delete same cluster. I think the premise
> of the test is incorrect. If one of the two commands are expected to fail,
> isnt that breaking Falcon's idempotent behavior?
