> For the following lines, when it runs into IOException, it does not clean up
> the files under /hbase/mobdir/.tmp and /hbase/mobdir/.tmp/.bulkload.
> It could be due to creating of new mob file or new reference file under
> .bulkload directory fails. Or when mob files from ./tmp to the mob region
> directory fails.
