Did your NameNode start up correctly? If on a local instance, you can verify this by running `jps -lm`. If jps isn't on your path, it should be located in $JAVA_HOME/bin.
If the NameNode is not running, check your Hadoop logs. The log you want should have "namenode" in the file name-- it should tell you want went wrong. I commonly see this when setting up a new instance if I forget to run `hadoop namenode -format`.
