Yifan Cai commented on CASSANDRA-16415: --------------------------------------- Thanks for looking into it. Agree that it is broken ATM. A bit more info that the "digest mismatch" error only occurs in *v3X* and not in *v4*, although the patch is present in both versions. > Broken test mixedModeReadColumnSubsetDigestCheck - > org.apache.cassandra.distributed.upgrade.MixedModeReadTest > ------------------------------------------------------------------------------------------------------------- > > 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: 4.0-beta > > > 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.
