Component/s: wal
> Support multi threads to clean oldWALs

> Key: HBASE-18309
> URL: https://issues.apache.org/jira/browse/HBASE-18309
> Project: HBase
> Issue Type: Improvement
> Components: wal

> 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.
