>                 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)
>  at org.apache.cassandra.distributed.upgrade.MixedModeReadTest.lambda$mixedModeReadColumnSubsetDigestCheck$0(MixedModeReadTest.java:63)
>  at org.apache.cassandra.distributed.upgrade.UpgradeTestBase$TestCase.run(UpgradeTestBase.java:171)
>  at 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.
