Josh Wills updated CRUNCH-268:
------------------------------
Attachment: CRUNCH-268.patch
The patch I came up with that uses MD5 hashes to keep the tuple names
consistent, unique, and relatively short.
> Crunch's internal Avro tuple schemas should have stable names

> A long time ago, I made a change that used random names for the custom Avro
> schemas that Crunch generates for processing tuple types (pairs, trips,
> etc.). I recently hit a use case where that randomization burned me when I
> was re-running some pipelines over checkpointed data that I serialized using
> Crunch's Avro schemas (Pair, in particular), so I think that we should change
> the tuple schemas to have stable names based on their constituent field
> schemas via an MD5 hash.
