             Summary: Hive table partition predicate not passed down correctly
                 Key: SPARK-14172
                 URL: https://issues.apache.org/jira/browse/SPARK-14172
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.6.1
            Reporter: Yingji Zhang
            Priority: Critical


When the hive sql contains nondeterministic fields,  spark plan will not push down the partition predicate to the HiveTableScan. For example:
-- consider following query which uses a random function to sample rows
SELECT *
FROM table_a
WHERE partition_col = 'some_value'
AND rand() < 0.01;

The spark plan will not push down the partition predicate to HiveTableScan which ends up scanning all partitions data from the table.
