> From the design doc, mob files are not involved in the normal HBase
> compaction process. This means deleted mobs would still take up space and
> that we never really merge mob files that accrue over time. Currently, MOBs
> depend on two external tools:
> 1) A TTL cleaner that removes mobs that have passed their TTL or exceeded
> minVersions.
> 2) A 'sweep tool' cleaner that remove mobs that have had their references
> deleted and merges small files into larger ones.
> Today the tools are triggered by admins. The longer term goal would be to
> integrate them into hbase such that by default mobs are cleaned. The tools
> will be preserved however so that advanced admins can disable automatic
> cleanups and manually trigger these compaction like operaitons. #1 would
> likely be a chore in the master while #2 requires some design work to
> integrate into hbase.
