Subject [jira] [Commented] (HDFS-1799) Refactor log rolling and filename management out of FSEditLog
Date Fri, 01 Apr 2011 17:01:06 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1799?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13014746#comment-13014746

Ivan Kelly commented on HDFS-1799:
----------------------------------

Have you looked at the newest design doc in 1580? It's changed so that JournalManager has
a smaller role, and is only ever used to create input and output streams. Unfortunately I've
been caught up with other stuff this week so I haven't been able to implement any of it. But
hopefully this weekend I'll be able to get around to it.

> This is somewhat similar to HDFS-1580, but less ambitious. While that JIRA focuses on
pluggability, this task is simply the minimum needed for HDFS-1073:
> - Refactor the filename-specific code for rolling, diverting, and reverting log streams
out of FSEditLog into a new class
> - Clean up the related code in FSEditLog a bit
> Notably, this JIRA is going to temporarily break the BackupNode. I plan to circle back
on the BackupNode later on this branch.
