MapReduce addressed this in MAPREDUCE-5053, and it looks like Tez needs a similar fix.

> Many codecs throw java.lang.InternalError when their native implementations encounter an error in the codec.  This is not treated like a fetch failure and instead is fatal to the task.  The task should treat codec errors during fetch like other fetch failures and retry, hopefully triggering a re-run of the upstream task if necessary.
