Apache Spark reassigned SPARK-22217: ------------------------------------ Assignee: (was: Apache Spark) > ParquetFileFormat to support arbitrary OutputCommitters > ------------------------------------------------------- > > Key: SPARK-22217 > URL: https://issues.apache.org/jira/browse/SPARK-22217 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.2.0 > Reporter: Steve Loughran > > Although you can choose which committer to write dataframes as parquet data > via {{spark.sql.parquet.output.committer.class}}, you get a class cast > exception if this is not a > {{org.apache.parquet.hadoop.ParquetOutputCommitter}} or subclass. > This is not consistent with the docs in SQLConf, which says > bq. The specified class needs to be a subclass of > org.apache.hadoop.mapreduce.OutputCommitter. Typically, it's also a subclass > of org.apache.parquet.hadoop.ParquetOutputCommitter. > It is simple to relax {{ParquetFileFormat}}'s requirements, though if the > user has set > {{parquet.enable.summary-metadata=true}}, and set a committer which is not a > ParquetOutputCommitter, then they won't see the data. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
