Ted Yu commented on HBASE-14417:

I was adding new test which does one more full table backup after the 
incremental restore and verifies that BulkLoadDescriptor's are cleaned up from 
It turns out the bulk loaded hfiles were renamed during the incremental restore 
which resulted in FileNotFoundException.

Filed HBASE-16672 so that the bulk loaded hfiles can be used for multiple 
restore destinations.

> Currently, incremental backup is based on WAL files. Bulk data loading 
> bypasses WALs for obvious reasons, breaking incremental backups. The only way 
> to continue backups after bulk loading is to create new full backup of a 
> table. This may not be feasible for customers who do bulk loading regularly 
> (say, every day).
