Jeff Zhang created TEZ-2271:
-------------------------------
Summary: OutputFormat is not recognized correctly
Key: TEZ-2271
URL: https://issues.apache.org/jira/browse/TEZ-2271
Project: Apache Tez
Issue Type: Bug
Reporter: Jeff Zhang
Assignee: Jeff Zhang
TEZ-2162 didn't resolve it completely. Paste the comment from TEZ-2162
bq. But there's one exceptional case that if user specify OutputFormat through
conf, then even MROutput is on mapper side, user still need to use property
MRJobConfig.NEW_API_REDUCER_CONFIG rather than NEW_API_MAPPER_CONFIG. Or I
think we can take useNewAPI as true as any of NEW_API_MAPPER_CONFIG,
NEW_API_REDUCER_CONFIG is set true (patch didn't include this now)
This issue happens when translating from Mapper-only MR job to tez.
