Spiros Ioannou updated CASSANDRA-14672:
---------------------------------------
Description:
We had 3.11.0, then we upgraded to 3.11.3 last week. We routinely perform
deletions as the one described below. After upgrading we run the following
deletion query:
{code:java}
DELETE FROM measurement_events_dbl WHERE measurement_source_id IN (
9df798a2-6337-11e8-b52b-42010afa015a, 9df7717e-6337-11e8-b52b-42010afa015a,
a08b8042-6337-11e8-b52b-42010afa015a, a08e52cc-6337-11e8-b52b-42010afa015a,
a08e6654-6337-11e8-b52b-42010afa015a, a08e6104-6337-11e8-b52b-42010afa015a,
a08e6c76-6337-11e8-b52b-42010afa015a, a08e5a9c-6337-11e8-b52b-42010afa015a,
a08bcc50-6337-11e8-b52b-42010afa015a) AND year IN (2018) AND measurement_time
>= '2018-07-19 04:00:00'{code}
Immediately after that, trying to read the last value produces an error:
{code:java}
select * FROM measurement_events_dbl WHERE measurement_source_id =
a08b8042-6337-11e8-b52b-42010afa015a AND year IN (2018) order by
measurement_time desc limit 1;
ReadFailure: Error from server: code=1300 [Replica(s) failed to execute read]
message="Operation failed - received 0 responses and 2 failures"
info={'failures': 2, 'received_responses': 0, 'required_responses': 1,
'consistency': 'ONE'}{code}
And the following exception:

We host those on GCE and recreated all the nodes with disk snapshots, and we
reproduced the error: after re-running the DELETE the error was reproduced
immediately.
We tried so far:
re-running repairs on all nodes and running nodetool garbagecollect with no
success.
We are currently testing downgrade to 3.11.2 hoping it will work, first test
show that 3.11.2 works ok after deletion. Please also inform us if you know
downgrading would cause any issues.
