I didn't mention it but the complete filesystem is reported healthy by fsck.
I'm guessing that the java.io.EOFException indicates a problem caused by the
load of the job.
Any ideas?
It's a very tricky work to debug a MapReduce Job execution but I'll try.

1- Did you check this?
2- Which are the file permisions on /user/emeij/icwsm-data-test/ ?
If the fsck command gives that all is fine, really I don't know more.
