Vihang Karajgaonkar reassigned HIVE-17875: ------------------------------------------ > Vectorization support for complex types breaks parquet vectorization > -------------------------------------------------------------------- > > Key: HIVE-17875 > URL: https://issues.apache.org/jira/browse/HIVE-17875 > Project: Hive > Issue Type: Bug > Components: Vectorization > Reporter: Vihang Karajgaonkar > Assignee: Vihang Karajgaonkar > > HIVE-16589 introduced support for complex types for vectorized execution. It > introduces two new configs {{hive.vectorized.complex.types.enabled}} and > {{hive.vectorized.groupby.complex.types.enabled}} which default to true and > control whether {{Vectorizer}} creates a vectorized execution plan for > queries using complex types. Since Parquet fileformat does not support > vectorization for complex types yet, any query running on parquet tables with > complex types current fails with a RuntimeException complaining that the > complex type is not supported. We should improve the logic in Vectorizer to > check if the FileinputFormat supports complex types and if not it should not > vectorize the query plan. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
