      Removed unused hbase.fs.tmp.dir from hbase-default.xml.

      Upped hbase.master.fileSplitTimeout from 30s to 10minutes (suggested by production experience)

      Added note that handler-count should be ~CPU count.

      hbase.regionserver.logroll.multiplier has been changed from 0.95 to 0.5 AND the default block size has been doubled.

      A few of the core configs are now dumped to the log on startup.
