The skipping feature should really only be used when you are calling
out to a third-party library that may segfault on corrupt data, and
even then it's probably better to use a subprocess to handles it, as
Owen suggested here:
In other cases you should handle the corrupt data in your mapper or
reducer, by catching the relevant exception, for example.
