Description

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.
