in PartitionedMobCompactor#bulkloadRefFile
If region num is changed from 1 to 20
bulkload will fail and we will get an exception
!image-2019-11-30-10-30-33-243.png!
and then delete bulkload path and new MobFile,
old mob file is not deleted.
but some hfiles have been successfully loaded through bulkload and not deleted.

And then,,,, get rowkey,,,,throw filenotfound
solution : write multiple hfiles and reduce split hfiles. because the data of
scanner is ordered，we just need to open a hfile at the same time, when the
current data dose not belong to the current hfile, we can close hfile and
create new hfile.
