Pankaj Kumar commented on HBASE-16509:
--------------------------------------
I meant, whether "private List<String> unmatchedFamilies" will have the
unmatched column families because in validateFamiliesInHFiles(...) it is added
locally,
{noformat}
List<String> unmatchedFamilies = new ArrayList<String>();
Iterator<LoadQueueItem> queueIter = queue.iterator();
while (queueIter.hasNext()) {
LoadQueueItem lqi = queueIter.next();
String familyNameInHFile = Bytes.toString(lqi.family);
if (!familyNames.contains(familyNameInHFile)) {
unmatchedFamilies.add(familyNameInHFile);
}
}
{noformat}
> Add option to LoadIncrementalHFiles which allows skipping unmatched column
> families

> 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.
