Since you're only just beginning, and have unknowingly issued multiple
"namenode -format" commands, simply run the following and restart DN
alone:

$ rm -r /private/tmp/hadoop-hadoop-user/dfs/data

(And please do not reformat namenode, lest you go out of namespace ID
sync yet again -- You can instead `hadoop dfs -rmr /*` to rid yourself
of all HDFS files)
