I have setup a Mapr cluster on Amazon EC2 and created a user 'user1' and provided all the necessary permissions to the user to run the hadoop jobs. I get the below error
Error initializing attempt_201302281837_0004_m_000002_0: Job initialization failed (255). with output: Reading task controller config from /opt/mapr/hadoop/hadoop-0.20.2/conf/taskcontroller.cfg

I have tried the solutions given in the mapr forums in the below link but still the issue persists

Can anyone help me here??
