[jira] [Created] (TEZ-4248) Tez should propagate projection pruning
properties to map operator
Marton Bod created TEZ-4248:
-------------------------------
Summary: Tez should propagate projection pruning properties to map operator
Key: TEZ-4248
URL: https://issues.apache.org/jira/browse/TEZ-4248
Project: Apache Tez
Issue Type: New Feature
Reporter: Marton Bod
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.
