Hi Mike,
This just leaves the parallelHF too-short-iterator, right? That error
in this context means that an exception was thrown in the iterator. I
wasn't able to reproduce it on your dataset ... if you change it to be
expaned rather than an iterator, it should show where and what the
exception is.
