Github user justinleet commented on the issue: https://github.com/apache/incubator-metron/pull/541 Taking a first glance through this and had a couple comments before I dig in a little further and spin things up. Can you flesh out the unit tests around the binary filtering? The converted unit tests are helpful, but it seems like there's probably more cases than are covered by the couple additions involving. I'm not familiar with the library, but does this work if I provide things in a '0x' hex format? E.g. your example has `BYTEARRAY_MATCHER('1F90', packet)` but will it still work if it's `BYTEARRAY_MATCHER('0x1F90', packet)`? I don't think it's necessary that it does, but I looked at the example and immediately suspected I'd have prepended '0x' to '1F90' out of pure habit.
