Patrick Wendell updated SPARK-5528: ----------------------------------- Assignee: Cheng Lian > Support schema merging while reading Parquet files > -------------------------------------------------- > > Key: SPARK-5528 > URL: https://issues.apache.org/jira/browse/SPARK-5528 > Project: Spark > Issue Type: Improvement > Reporter: Cheng Lian > Assignee: Cheng Lian > Fix For: 1.3.0 > > > Spark 1.2.0 and prior versions only reads Parquet schema from {{_metadata}} > or a random Parquet part-file, and assumes all part-files share exactly the > same schema. > In practice, it's common that users append new columns to existing Parquet > schema. Parquet has native schema merging support for such scenarios. Spark > SQL should also support this. -- 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
