I suspect only changes needed are in > org.apache.spark.internal.io.HadoopMapReduceCommitProtocol, which already has > a flag for dynamicPartitionOverwrite. I got a quick test to work by disabling > all committer activity (committer.setupJob, committer.commitJob, etc.) when > dynamicPartitionOverwrite is true. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
