Todd Lipcon updated HDFS-1799:
------------------------------

    Attachment: hdfs-1799.txt

Slightly improved patch. I had forgotten to update the "state" variable in FSEditLog on divert
and purge.

> 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.
