Owen O'Malley created HIVE-4250: ----------------------------------- Summary: Closing lots of RecordWriters is slow Key: HIVE-4250 URL: https://issues.apache.org/jira/browse/HIVE-4250 Project: Hive Issue Type: New Feature Components: Serializers/Deserializers Reporter: Owen O'Malley Assignee: Owen O'Malley
In FileSinkOperator, all of the RecordWriters are closed sequentially. For queries with a lot of dynamic partitions this can add substantially to the task time. For one query in particular, after processing all of the records in a few minutes the reduces spend 15 minutes closing all of the RC files. -- This message is automatically generated by JIRA.
