Zhan Zhang commented on SPARK-11087: ------------------------------------ no matter whether the table is sorted or not, the predicate pushdown should happen. Need to first add some debug msg on the driver side to make sure it happen. > spark.sql.orc.filterPushdown does not work, No ORC pushdown predicate > --------------------------------------------------------------------- > > Key: SPARK-11087 > URL: https://issues.apache.org/jira/browse/SPARK-11087 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.5.1 > Environment: orc file version 0.12 with HIVE_8732 > hive version 1.2.1.2.3.0.0-2557 > Reporter: patcharee > Priority: Minor > > I have an external hive table stored as partitioned orc file (see the table > schema below).
