> During my work on HBASE-15449, there came the need for LoadIncrementalHFiles not to bail
out on unmatched column families.
> The use case is like this:
> * table has two column families, A and B
> * full backup is taken on this table
> * column family B is dropped
> * more data is written to the table
> * incremental backup is performed on the table
> * user performs incremental restore using the latest backup
> Since column family B is gone, LoadIncrementalHFiles would fail with IOException for
family mismatch.
> This issue is to add an option to LoadIncrementalHFiles so that bulk load can load hfiles
for the existing column families.
