------------------------------------
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.
