Adric Eckstein created CRUNCH-573:
-------------------------------------
Summary: Avro union in cogroup doesn't check for nested unions
Key: CRUNCH-573
URL: https://issues.apache.org/jira/browse/CRUNCH-573
Project: Crunch
Issue Type: Bug
Affects Versions: 0.13.0
Reporter: Adric Eckstein
If one of the Cogroup.cogroup() inputs PType is an avro union, the cogroup()
method attempts to construct a union of the input PTypes, which throws a Avro
RuntimeException for a nested union. This is similar to CRUNCH-547.
The bug could be fixed by either modifying the Avros.unionOf() method to check
for union input types, or by unnesting the types in cogroup() prior to
constructing the avro union.
