Sylvain Lebresne commented on CASSANDRA-11302:
----------------------------------------------
No reason to not get that fix quickly so pushed a fix that uses the
{{isTimedOut}} method instead:
|| patch || utests || dtests ||
| [2.1|https://github.com/pcmanus/cassandra/commits/11302-2.1] |
[utests|http://cassci.datastax.com/job/pcmanus-11302-2.1-testall] |

[dtests|http://cassci.datastax.com/job/pcmanus-11302-2.2-dtest] |
| [3.0|https://github.com/pcmanus/cassandra/commits/11302-3.0] |
[utests|http://cassci.datastax.com/job/pcmanus-11302-3.0-testall] |
[dtests|http://cassci.datastax.com/job/pcmanus-11302-3.0-dtest] |
The tests on 2.1 and 2.2 are on par with their main branches, the 3.0 runs had
a few additional failures which are probably unrelated but I've re-started them
to check. [~aweisberg], mind having a look (all the versions are the same, they
merge up from 2.1 without conflict)?
> Invalid time unit conversion causing write timeouts
> ---------------------------------------------------
>
> Key: CASSANDRA-11302
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11302
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Mike Heffner
> Attachments: nanosec.patch
>
>
> We've been debugging a write timeout that we saw after upgrading from the
> 2.0.x release line, with our particular workload. Details of that process can
> be found in this thread:
> https://www.mail-archive.com/user@cassandra.apache.org/msg46064.html
> After bisecting various patch release versions, and then commits, on the
> 2.1.x release line we've identified version 2.1.5 and this commit as the
> point where the timeouts first start appearing:
> https://github.com/apache/cassandra/commit/828496492c51d7437b690999205ecc941f41a0a9
> After examining the commit we believe this line was a typo:
> https://github.com/apache/cassandra/commit/828496492c51d7437b690999205ecc941f41a0a9#diff-c7ef124561c4cde1c906f28ad3883a88L467
> as it doesn't properly convert the timeout value from milliseconds to
> nanoseconds.
> After testing with the attached patch applied, we do not see timeouts on
> version 2.1.5 nor against 2.2.5 when we bring the patch forward. While we've
> tested our workload against this and we are fairly confident in the patch, we
> are not experts with the code base so we would prefer additional review.
