            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.
