Reid Chan commented on HBASE-18309:
-----------------------------------
I think both can be unified, since they have same chore() methods, the
differences are how to validate file and how to delete them. [~carp84]
Thanks for your advice, i'm doing tests mentioned above, and then will see the
online configuration change.

> 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.
