You have to use this command to format
hdfs namenode –format
not hdfs dfs -format

Hi, thanks for your answers.
Sorry, I forgot to add it, I couldn´t run the command neither:
C:\development\tools\hadoop%HADOOP_PREFIX%\bin\hdfs dfs -format
-format: Unknown command
C:\development\tools\hadoopecho %HADOOP_PREFIX%
C:\development\tools\hadoop
By using –help command there is no format param.
My Hadoop version: 2.4.0 (the latest version supported by mongo-hadoop).
Best regards,
Blanca

Have you formatted HDFS (step 3.4)?

Trying to get running the mapreduce-example indicated in the pont 3.6, I get
the connection exception again. Tha brings me to the
http://wiki.apache.org/hadoop/ConnectionRefused page where the exception in
explained. So I guess I have some misunderstandings with the configuration.
I tried to find information about that and found the page
http://wiki.apache.org/hadoop/HowToConfigure but is still not very clear for
me.
I attach my config files, the ones I modified maybe you can help me out…
Many thanks!!
