Date Thu, 29 Jun 2017 22:35:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16069126#comment-16069126
] 

Jun Rao commented on KAFKA-5542:
--------------------------------

We can clarify the following.

"During the upgrade phase when some existing messages may not have a leader epoch, if requestedEpoch
is < the first epoch in epochs, we want to return UNSUPPORTED_EPOCH_OFFSET so that the
follower can fall back to HW."

> Improve Java doc for LeaderEpochFileCache.endOffsetFor()
