Sylvain Lebresne updated CASSANDRA-5284:
----------------------------------------
Attachment: 5284.txt
> Possible assertion triggered in SliceFromReadCommand
> ----------------------------------------------------
>
> Key: CASSANDRA-5284
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5284
> Project: Cassandra
> Issue Type: Bug
> Reporter: Sylvain Lebresne
> Assignee: Sylvain Lebresne
> Priority: Minor
> Fix For: 1.1.11
>
> Attachments: 5284.txt
>
>
> In SliceFromReadCommand.maybeGenerateRetryCommand, the following assertion
> {noformat}
> assert maxLiveColumns <= count;
> {noformat}
> may actually fail. Namely, it asserts that no node has returned more columns
> that what was asked for, which in general is true, but can not be if an
> expiring column is counted as dead by the replica (but still send as a
> tombstone) but, due to clock difference, is actually counted live by the
> coordinator.
> I note that this is similar to CASSANDRA-5149 in that fixing CASSANDRA-5149
> would fix this too, but in the meantime, this edge case is harmless so there
> is probably not much point in keeping the assertion.
