Soluzione

Formate your namenode...Start hadoop system and then...

just to store file, you can use 

hadoop fs -copyFromLocal File.xml /

To check your file is stored on HDFS run this... or in web-browser type this URL "hostname:50070" - hostname==IP address of machine on which hadoop namenode is installed. (if this is not a single node cluster).

hadoop fs -ls /

To read file on HDFS from shell 

hadoop fs -cat /file.xml
