HI Ali,
I also faced this error when i ran the jobs either in local or in a cluster.
I am able to solve this problem by removing the .crc file created in the
input folder for this job.
Please check that there is no .crc file in the input.
I hope this solves the problem.

Hi Oliver,
I am not sure my suggestion might solve your problem or it might be already
solved on your side.
It seems the task tracker is having a problem accessing the tmp directory.
Try going to the core and mapred site xml and change the tmp directory to a
new one.
