huaxiang sun updated HBASE-17250:
---------------------------------
    Attachment: HBASE-17250-master-001.patch

Upload an initial patch. May not be a good idea to expose implementation details through getScanner() interface. But I could find a way to better pass the flag around. There are other places such as

https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java#L6894

which similar skipCheckFamily can be applied. If folks agrees that this is the right approach to take, will upload a comprehensive patch, thanks.

> For get(), checkFamily is done in prepareGet(), so checkFamily can be skipped in Region#getScanner(). For scan(), if there is no Family configured in scan, the families are from table descriptor, so checkFamily in Region#getScanner(). can be skipped in this case.
