Jeff Zhang updated TEZ-2271:
----------------------------
Priority: Critical (was: Major)
> 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
> Priority: Critical
>
> 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.
