             Summary: Crunch's internal Avro tuple schemas should have stable names
                 Key: CRUNCH-268
                 URL: https://issues.apache.org/jira/browse/CRUNCH-268
             Project: Crunch
          Issue Type: Bug
          Components: Core, IO
    Affects Versions: 0.7.0
            Reporter: Josh Wills
            Assignee: Josh Wills


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.
