Subject [jira] [Commented] (KAFKA-748) Append to index fails due to invalid offset
Date Thu, 07 Feb 2013 22:55:12 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13574021#comment-13574021

Jay Kreps commented on KAFKA-748:
---------------------------------

This is actually very easy to reproduce. Just do a clean shutdown on the broker while running
the producer perf test. Haven't debugged it yet.

> We seem to be appending to the index and it checks to make sure we do not insert an entry
with an offset that is larger than the actual offset of the message. We seem to be trying
to insert an offset = 1 in the index while lastOffset is 24463. This seems to get fixed on
restarting the broker.
> java.lang.IllegalArgumentException: Attempt to append an offset (1) to position 21703
no larger than the last offset appended (24463).
