Jean-Daniel Cryans commented on HBASE-3904:
-------------------------------------------

On the new v5 (should have been v6?):

 - I don't think you need to keep that map of regions, all you really want is a count? Like
it's creating the map with the hostAndPort possibly null and the rest of the code couldn't
care less. I think you could keep a counter and reset it when you loop.
 - About that hostAndPort, if it's null should you consider that region as unassigned and
not counted as an available region?

> This function as per the java doc is supposed to return true iff "all the regions in
the table are available". But if the table is still being created this function may return
inconsistent results (For example, when a table with a large number of split keys is created).
