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. !image-2019-11-30-10-27-57-345.png!
