>                 Key: SPARK-17091
>                 URL: https://issues.apache.org/jira/browse/SPARK-17091
>             Project: Spark
>          Issue Type: Bug
>            Reporter: Andrew Duffy
>
> Past attempts at pushing down the InSet operation for Parquet relied on user-defined
predicates. It would be simpler to rewrite an IN clause into the corresponding OR union of
a set of equality conditions.
