[jira] [Commented] (CASSANDRA-12206) CommitLogTest.replaySimple failure

["Joshua McKenzie (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-12206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15379833#comment-15379833 ] 

Joshua McKenzie commented on CASSANDRA-12206:
---------------------------------------------

Failed once out of 200 runs locally. A little inspection and thought led me to change the SimpleCountingReplayer in CommitLogTest to take a CFMetaData and only count mutations for the CF you're filtering for. There's a chance that other system mutations can end up in the commitlog and expecting a segment to only have a certain count of mutations is flaky and incorrect.
