Dieudonne,

I observed that one of the data node was dead and just I started the all hadoop services again. Now map reduce is working , the problem was one of the nodes was dead.
Happy coding.

hi Dieudonne,

Please correct the output path and also check if the datanode is up in the "Cloudera manager services " page
