> Issue Type: New Feature
> Components: PXF

> Assignee: Shivram Mani
> Fix For: 2.0.1.0-incubating

>
> HiveORCAccessor will be a subclass of the existing HiveAccessor with support
> for Predicate Pushdown and Column projection.
> We will be using the job configuration object which is used by the ORC
> reader. This will still be a record based reader and not batch/vector based
> We will map the filter information passed from HAWQ via PXF into
> SearchArgument object and set in sarg.pushdown configuration property.
> We will populate the column info passed from HAWQ (HAWQ-927) into the
> following configuration properties
> hive.io.file.readcolumn.ids, hive.io.file.readcolumn.names.
> hive.io.file.read.all.columns will be set to false.
