Hello,
Sorry for the late response. Looks like you haven't formatted your
NameNode (seeing your ls outputs against hdfs-site.xml). The
dfs.name.dir does not exist when the NN tries to check for it, and
that is why your startup fails.
Have you done the "hadoop namenode -format" step of the setup yet?
