Subject [jira] [Created] (SPARK-17357) Simplified predicates should be able to pushdown through operators
Date Thu, 01 Sep 2016 06:38:20 GMT
Liang-Chi Hsieh created SPARK-17357:
---------------------------------------

             Summary: Simplified predicates should be able to pushdown through operators
                 Key: SPARK-17357
                 URL: https://issues.apache.org/jira/browse/SPARK-17357
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Liang-Chi Hsieh


In Optimizer, Filter operator will go through the rules PushDownPredicate, CombineFilters
and BooleanSimplification.

Under this rule order, it is possibly that some predicates that should be able to push down,
can't be pushed down through operators.

We should fix it.
