---------------------------------
Attachment: HBASE-17250-master-002.patch
Submit a patch. One issue with coprocessor is that it could change families in
scan, to be safe, after coprocessor, recheck families in getScanner().
> For Get and scan in one case, checkFamily can be skipped in Region#getScanner
