Andres de la Peña commented on CASSANDRA-16415:
-----------------------------------------------
Thanks for the changes. There are still a few unneeded {{throws Exception}} on
the column filter test for 3.11 and trunk that I can easily remove on commit,
if that's ok for you. Other than this nit the changes look good to me.
It seems that the runs in ci-cassandra above took longer than usual which I
think can produce some test failures, I have re-run those runs:
* [ci-cassandra
3.0|https://ci-cassandra.apache.org/blue/organizations/jenkins/Cassandra-devbranch/detail/Cassandra-devbranch/418/pipeline]
* [ci-cassandra
3.11|https://ci-cassandra.apache.org/blue/organizations/jenkins/Cassandra-devbranch/detail/Cassandra-devbranch/417/pipeline]
* [ci-cassandra
trunk|https://ci-cassandra.apache.org/blue/organizations/jenkins/Cassandra-devbranch/detail/Cassandra-devbranch/416/pipeline]
Curiously it seems that for 3.11 the tests
{{SASIIndexTest#testIndexRedistribution/testPagination}} fail consistently,
when they were occasionally flaky without the patch. Nevertheless the flakiness
of these tests is being addressed in CASSANDRA-16444 so I think it's safe to
consider the failures as not related.
[~yifanc] if the CI results above look good to you I can proceed to commit.

> Key: CASSANDRA-16415
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16415
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Coordination, Test/dtest/java
> Reporter: Yifan Cai
> Assignee: Jacek Lewandowski
> Priority: Normal
> Fix For: 3.11.x, 4.0-beta
>
> Time Spent: 8h 40m
> Remaining Estimate: 0h
>
> The test has been failing and can always be reproduced in the recent CI.
> Stack trace:
> {code:java}
> junit.framework.AssertionFailedError: Found Digest Mismatch
> at
> org.apache.cassandra.distributed.upgrade.MixedModeReadTest.checkTraceForDigestMismatch(MixedModeReadTest.java:89)

> org.apache.cassandra.distributed.upgrade.MixedModeReadTest.lambda$mixedModeReadColumnSubsetDigestCheck$0(MixedModeReadTest.java:63)

> org.apache.cassandra.distributed.upgrade.MixedModeReadTest.mixedModeReadColumnSubsetDigestCheck(MixedModeReadTest.java:76)
> {code}
> The initial investigation shows that
> * The test only fails in the setup phase of
> mixedModeReadColumnSubsetDigestCheck. The cluster version is
> *Versions.Major.v3X*
> * The test failure is likely a consequence of CASSANDRA-15962. After
> dropping the commit in branch cassandra-3.11 and rebuild the dtest jar, the
> upgrade test can pass. Meanwhile, dropping the other commits does not help.
