-------------------------------

[~reidchan] Yes. Its chatty. I can cut it back. The "Couldn't delete..." is unsettling though.
You think it because new files. Can we give operator a better message? If you suggest one,
I can add it in sir. Thanks.

> There is only one thread in LogCleaner to clean oldWALs and in our big cluster we find
this is not enough. The number of files under oldWALs reach the max-directory-items limit
of HDFS and cause region server crash, so we use multi threads for LogCleaner and the crash
not happened any more.
> What's more, currently there's only one thread iterating the archive directory, and we
could use multiple threads cleaning sub directories in parallel to speed it up.
