Shivram Mani updated HAWQ-931:
------------------------------
Description:
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.
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.
