Hyukjin Kwon updated SPARK-9935:
--------------------------------
Component/s: SQL
> EqualNotNull not processed in ORC
> ---------------------------------
>
> Key: SPARK-9935
> URL: https://issues.apache.org/jira/browse/SPARK-9935
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Hyukjin Kwon
> Priority: Minor
>
> it is a following issue of the issue, SPARK-9814.
> Now datasources (after {{selectFilters()}} in
> {{org.apache.spark.sql.execution.datasources.DataSourceStrategy}}) can pass
> {{EqualNotNull}} to relations but {{OrcRelation}} does not take and process
> this.
> (ParquetRelation has also the same issue but it seems Parquet does not
> support the null-safe equal filter. It is confusing whether Parquet should
> support this or treat this as EqualFilter with additional codes in Spark
> code. Therefore, I made a separate issue only for ORC)
