whose underlying Parquet type is an ENUM (was: Parquet shouldn't push down
predicates over a column whose underlying Parquet type is an ENUM)

> Key: SPARK-9407
> URL: https://issues.apache.org/jira/browse/SPARK-9407
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.0
> Reporter: Cheng Lian
> Assignee: Cheng Lian
> Priority: Blocker
>
> Spark SQL doesn't have an equivalent data type to Parquet {{BINARY (ENUM)}},
> and always treats it as a UTF-8 encoded {{StringType}}. Thus, predicate over
> a Parquet {{ENUM}} column may be pushed down. However, Parquet 1.7.0 and
> prior versions only support filter push-down optimization for [a limited set
> of data
> types|https://github.com/apache/parquet-mr/blob/apache-parquet-1.7.0/parquet-column/src/main/java/org/apache/parquet/filter2/predicate/ValidTypeMap.java#L66-L80],
> and fails the query.
> The simplest solution seems to be upgrading parquet-mr to 1.8.1, which fixes
> this issue via PARQUET-201
