Subject [jira] [Commented] (HBASE-6337) [MTTR] Remove renaming tmp log file in SplitLogManager
Date Tue, 10 Jul 2012 20:38:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13410864#comment-13410864
] 

Zhihong Ted Yu commented on HBASE-6337:
---------------------------------------

I ran TestHLog with patch v4 3 times and they passed on MacBook.

It is a pity that builds on PreCommit-HBASE-Build were truncated to July 4th - the first link
above is no longer working.

Looks like Chunhui has answered all the questions.
The 0.94 equivalent of the patch was running in their dev cluster.

Will wait for 24 hours for further comments.

> As HBASE-6309 mentioned, we also encounter problem of distributed-log-splitting take
much more time than matser-local-log-splitting because lots of SplitLogManager 's renaming
operations when finishing task.
> Could we try to remove renaming tmp log file in SplitLogManager through splitting log
to regions' recover.edits directory directly as the same as the master-local-log-splitting.
