Todd Lipcon updated HDFS-1462:
------------------------------
Attachment: hdfs-1462.txt
New patch moves all logs in FSEditLog.java to its own log instance. I also
removed the following log message:
{code}
- if(FSImage.LOG.isDebugEnabled()) {
- FSImage.LOG.debug("loggin edits into " + eStream.getName() +
- " stream");
- }
{code}
which was added post 0.20 and seems way too verbose to be useful (logs once per
edit per log stream!). Hope that's OK.
> Refactor edit log loading to a separate class from edit log writing

> Before the major work in HDFS-1073, I'd like to do this refactor to clean up
> the monster FSEditLog class. We can separate all the functions that take of
> loading edits into an FSN from the functions that take care of writing edits,
> rolling, etc.
