             Summary: Get path validates column families twice
                 Key: HBASE-11034
                 URL: https://issues.apache.org/jira/browse/HBASE-11034
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Nick Dimiduk
            Assignee: Nick Dimiduk
            Priority: Minor


HRegion#get(Get) adds/validates column families. The resulting RegionScanner 
goes through the same validation dance a second time. That second 
implementation is slightly less efficient, always checking the families, even 
if there were no user-provided families and the prepareScanner() call already 
did this. The current logic in HRegion#get() is smarter actually. Let's do the 
work only once.
