Description

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.
