I'm trying to do a hadoop single node installation.
I am following this article for hadoop installation instructions. One of the steps I need to do is to format the hadoop file system using the command
hduser@dbserver:~/hadoop/conf$ /home/hduser/hadoop/bin/hadoop namenode -format
hduser@dbserver:~/hadoop/conf$ /home/hduser/hadoop/bin/hadoop namenode -format

i get the above error message when trying to format
Any suggestions to fix this issue are welcome :) .
