             Summary: Add option to LoadIncrementalHFiles which allows skipping unmatched
column families
                 Key: HBASE-16509
                 URL: https://issues.apache.org/jira/browse/HBASE-16509
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu
            Assignee: Ted Yu


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.
