> The MOB files are involved in the HBase compaction. It means there's no chance to delete and merge the MOB files. The external tools do this, one is a cleaner to clean the MOB files that are expired (by TTL and minVersions), the other one is a sweep tool to clean the deleted Cells in HBase and merge small files into bigger ones. These tools are triggered by users. Besides, the cleaner could be a chore in HMaster.
