[jira] [Created] (CRUNCH-268) Crunch's internal Avro tuple schemas
should have stable names
Josh Wills created CRUNCH-268:
---------------------------------
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.
