Jacek Lewandowski updated CASSANDRA-16515:
------------------------------------------
Description:
When {{ViewFilteringTest}} creates a view, it is added to the list of created
views. Those views are removed after each test cases. If creating a view fail,
it is not added to the list of views to be dropped because the assumption is
that when the command fails, the view should not be created. This is ok in
general however it is not a valid assumption when we get operation timed out
because we cannot say anything about its real result. This way, it is possible
that the view gets created, the driver throws time out and we do not remove the
created view. All other test cases which tries to create that view will fail
because the view already exists.
While it seems very improbable, we actually hit this a couple of times on our
infrastructure
