Ashutosh Chauhan created HIVE-3950: -------------------------------------- Summary: Remove code for merging files via MR job Key: HIVE-3950 URL: https://issues.apache.org/jira/browse/HIVE-3950 Project: Hive Issue Type: Improvement Components: Query Processor Reporter: Ashutosh Chauhan
Hive can merge files either via MR job or via map only job. Obviously, doing it via map-only job is more efficient, but there is an option of doing it via MR job as well because CombineFileInputFormat is available only in hadoop-0.20 and later. Since, we no longer support hadoop versions earlier than 20 anymore all that is now dead code, we should get rid of it. -- This message is automatically generated by JIRA.
