Oh, HBASE-1102, I see it in the history now. Sorry if this is a dupe and it does the above
then please disregard this issue and close accordingly.

> Currently one has to use get() != null checks to see if a specific column has a value
for any given row. But this involves the whole load and transfer stack to shift the data to
the client just for it to drop the content. Better would be a server side check and only returning
the boolean back to the client, especially if the checked cell is containing MB's of data.
