> As HBASE-6309 mentioned, we also encounter problem of distributed-log-splitting take
much more time than matser-local-log-splitting because lots of SplitLogManager 's renaming
operations when finishing task.
> Could we try to remove renaming tmp log file in SplitLogManager through splitting log
to regions' recover.edits directory directly as the same as the master-local-log-splitting.
