Mitesh updated SPARK-17636:
---------------------------
Affects Version/s: 1.6.3
> Parquet filter push down doesn't handle struct fields
> -----------------------------------------------------
>
> Key: SPARK-17636
> URL: https://issues.apache.org/jira/browse/SPARK-17636
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, SQL
> Affects Versions: 1.6.2, 1.6.3
> Reporter: Mitesh
> Priority: Minor
>
> Theres a *PushedFilters* for a simple numeric field, but not for a numeric
> field inside a struct. Not sure if this is a Spark limitation because of
> Parquet, or only a Spark limitation.
> {quote}
> scala> hc.read.parquet("s3a://some/parquet/file").select("day_timestamp",
> "sale_id")
> res5: org.apache.spark.sql.DataFrame = [day_timestamp:
> struct<timestamp:bigint,timezone:string>, sale_id: bigint]
> scala> res5.filter("sale_id > 4").queryExecution.executedPlan
> res9: org.apache.spark.sql.execution.SparkPlan =
> Filter[23814] [args=(sale_id#86324L >
> 4)][outPart=UnknownPartitioning(0)][outOrder=List()]
> +- Scan ParquetRelation[day_timestamp#86302,sale_id#86324L] InputPaths:
> s3a://some/parquet/file, PushedFilters: [GreaterThan(sale_id,4)]
> scala> res5.filter("day_timestamp.timestamp > 4").queryExecution.executedPlan
