-------------------------------------
@ram
Through the log, we found writer.close() took about 30ms~50ms.
So, it will took about 20s if there are 400 regions in one hlog file.

> First，we do the test between local-master-split and distributed split log
> Environment：34 hlog files, 5 regionservers,(after kill one, only 4 rs do ths
> splitting work)
> local-master-split:60s+
> distributed-split-log:165s+
> In fact, in our production environment, distributed-split-log also took 60s
> with 30 regionservers for 34 hlog files (regionserver may be in high load)
> We found split-worker split one log file took about 20s.
> I think we should do the improvement for this.
