Major Description
The bulk import FATE operation LoadFile bulk imports files and copies failed files. If master dies in the middle of coping the failed files, when it restarts it will start the FATE op from the beginning. In this situation previously failed files could succeed. However the failed files would still be in the fail dir. To overcome this the copying for failed files could be a follow on FATE op, of the FATE op could clear the failed dir before copying to make idempotent.
