Subject Re: About ant Hadoop

Can you please look at the jobtracker and tasktracker logs on nodes
where the task has been launched ? Also see if the job logs are
picking up anything. They'll probably give you clues on what is
happening.

Also, is HDFS ok ? i.e. are you able to read files already loaded etc.

Thanks
