Lars George commented on HBASE-2374:
------------------------------------
Hey KayKay,
I was wondering what that actually helps? You can already specify a combination
of columns or families with the existing parameter. If you leave out a ":"
divider then it is internally treated as a column family and addFamily is
called, if it *does* have a colon divider then it parses out family and column
and adds them together. Please advise.
