<br>
Your messages include "cloudera@localhost's password", which
probably means you didn't set up ssh localhost login without
password. It might cause some problems.<br>
<br>
One more thing worthy to be noted is that you should run
bin/format-namenode.sh
<meta charset="utf-8">
before bin/start-hadoop.sh to format namenode.<br>

I'm trying to run the examples of Hadoop on Kepler 2.4,
