[jira] [Commented] (CASSANDRA-4730) CommitLogReplayer should report the bad CRC checksum in the log

    [ https://issues.apache.org/jira/browse/CASSANDRA-4730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13698088#comment-13698088 ] 

Eric Lubow commented on CASSANDRA-4730:
---------------------------------------

The one thing I would like to advocate against is that Cassandra should not fail to start if there is a corrupt CommitLog.  It should throw a nasty error in the logs but not fail to load entirely.  I think the default behavior should be leaning towards availability and the server should be able to start just ignoring the corrupt CommitLog.

> If commit log isn't fully fsynced, the record which fails the checksum is not replayed do this logic. It would be beneficial to log that as an error so that user can know easily what happened.
