Subject [jira] [Commented] (CASSANDRA-4730) CommitLogReplayer should report the bad CRC checksum in the log
Date Sat, 06 Jul 2013 01:09:49 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13701212#comment-13701212
] 

Jonathan Ellis commented on CASSANDRA-4730:
-------------------------------------------

AFAIK we only fail the startup if we can't actually read the bits off the disk, which augurs
poorly for your odds of doing anything useful with it later.

> 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.
