Subject [jira] Commented: (HBASE-1483) HLog split loses track of edits
Date Fri, 05 Jun 2009 00:52:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1483?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12716469#action_12716469

stack commented on HBASE-1483:

I think there's another issue in here Clint.  Edits are coming out of the split file in reverse
order... the newest first (It looks like its the LinkedList that is issue)... checking.

>             Project: Hadoop HBase

>                   queue.push(new HLogEntry(val, key));
> The same val and key references are used in the iterator, so they keep changing their
contents as we .next() through the loop.
> Thus, when we are done, all the HLogEntries in logEntries will have the same HLogEdits
and HLogKeys! I don't think this would have ever worked unless there is only one region in
the log being split.
