a little bug :)

Hbase version: 0.90.2

" leastloaded=" + serversByLoad.lastKey().getLoad().getNumberOfRegions());

Should be:

" leastloaded=" + serversByLoad. firstKey ().getLoad().getNumberOfRegions());



if(serversByLoad.lastKey().getLoad().getNumberOfRegions() <= ceiling &&
       serversByLoad.firstKey().getLoad().getNumberOfRegions() >= floor) {
      // Skipped because no server outside (min,max) range
      LOG.info("Skipping load balancing.  servers=" + numServers + " " +
          "regions=" + numRegions + " average=" + average + " " +
          "mostloaded=" + 
serversByLoad.lastKey().getLoad().getNumberOfRegions() +
          " leastloaded=" + 
serversByLoad.lastKey().getLoad().getNumberOfRegions());
      return null;
    }
