[jira] [Commented] (KAFKA-804) Incorrect index in the log of a follower

    [ https://issues.apache.org/jira/browse/KAFKA-804?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13605568#comment-13605568 ]

Jay Kreps commented on KAFKA-804:
---------------------------------

Also:
- the offsets tuple gets recreated which isnt needed
- the count that is being done in analyzeAndValidateMessageSet is wrong and not being used. It should be removed (this can happen on trunk).

> In the follower, in log.append(), we use the offset of the 1st compressed message as the offset for appending index entries. This means that the index is pointing to an earlier position in the file than it should.  Instead, it should use the offset of the 1st uncompressed message for appending index.
