Sam Tunnicliffe commented on CASSANDRA-12651:
---------------------------------------------
I'm not convinced that the issue is a name clash. Where we've previously seen
name clashes (CASSANDRA-12834 for instance, which is the same failure as
reported in the 2 supplementary CI runs mentioned above), the problem is reuse
of an identifier by different tests within a fixture. In that case, the async
cleanup in the teardown races with a CREATE statement. Here though, the index
name is not reused anywhere and if it were, the CREATE INDEX has no IF NOT
EXISTS, so we'd likely see that request rejected rather than spurious query
results.
What seems odd to me is that in all of the SecondaryIndexTest failures above,
the invalid results are returned only after flush. That is, the test does:
{code}
run query X;
flush;
run query X;
{code}
So on each occasion, the exact same query executes and returns the expected
results almost immediately prior to failure. I accept that 7 test runs is a
small sample, but to me it points towards something flush related.
I've added some logging to try and pin down the cause a bit better, but as
[~ifesdjeen] noted, this is pretty damn hard to repro on demand, so I've been
running the test in pretty much a constant loop, but so far had no luck. I'll
update if/when I see a failure.
