Cheng Lian updated SPARK-9407: ------------------------------ Summary: Parquet shouldn't fail when pushing down predicates over a column whose underlying Parquet type is an ENUM (was: Parquet shouldn't push down predicates over a column whose underlying Parquet type is an ENUM) > Parquet shouldn't fail when pushing 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
