Answer 1

15/08/28 18:45:22 INFO namenode.NameNode: createNameNode [–format]

This looks like the same problem detailed here , with solution here .

The problem is that you used the long hyphen "–" instead of the short hyphen (minus symbol) "-"

One way that this can happen is by using a word processor instead of a text editor.

Answer 2

Seems you used a wrong command.The commands related to hdfs are available in this url

Use any of the following command command

hadoop namenode -format

OR

hdfs namenode -format
