> Clusters > 10 are less frequent that smaller clusters.  Defaults for when messages
are sent from regionserver to master would seem to favor clusters that are much larger than
ten nodes.  This issue is about changing them so the basic hbase setup is more live.  Its
about downing the interval between RS sending messages from 3 to 1 second and of making clients
retry more frequently at least at the start of the timeout period so they pick up changes
the quicker.  This should help with stuff like noticing splits and new regions coming on line.
 See HBASE-1892 for background.
