Michael Armbrust commented on SPARK-2883:
-----------------------------------------

#1 should be easy, that information is already there in HiveTableScan.  It just 
needs to propagated in the HiveConf.  We already use ColumnProjectionUtils, but 
I guess that is not enough? [See 
here|https://github.com/apache/spark/blob/master/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/HiveTableScan.scala#L80]
#2 Should also be pretty easy.  We can modify the planner to include predicates 
even if they are not partition pruning.
#3 I'm not clear if this is possible.  Is ORC self describing like parquet is?
