Hi Viet,
It looks your Hadoop namenode was not correctly formatted and
started. It's a very common hadoop problem. The solution I usually use
is 1) first kill running hadoop processes if you have any; 2) clean the
files and directories; 3) try namenode format again. In your case, the
clean command should be "rm -rf /tmp/hadoop-cloudera*"
Best wishes
Sincerely yours

Hi Mr. Jianwu Wang,
Thanks for for answer, the cloudera@localhost's password is already
entered (it's not showed in the screen as usual). I have changed the
the permission to the /root/ user, but it's not run yet.
I have tried to run bin/format-namenode.sh, it seems better but there
exist still errors:
/localhost/127.0.0.1:54310 <http://127.0.0.1:54310>. Already tried 0

Bad connection to FS. command aborted

If you have some advises for this problem?/

Hi Viet,
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.
One more thing worthy to be noted is that you should run
bin/format-namenode.sh before bin/start-hadoop.sh to format
namenode.
Best wishes
Sincerely yours
