> 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.
