> Key: TEZ-4248
> URL: https://issues.apache.org/jira/browse/TEZ-4248
> Project: Apache Tez
> Issue Type: New Feature
> Reporter: Marton Bod
> Priority: Major
> Attachments: TEZ-4248.1.patch
>
>
> MRReaderMapred should include projection pruning properties set during its
> initialization in its incremental config changes (accessible via
> getConfigUpdates()).
> This allows the hive serde to have access to these properties during
> initialization and therefore to construct the correct object inspector with
> only the selected columns.
