Kevin Wilfong created HIVE-3593: ----------------------------------- Summary: Output files of SMB join grow indefinitely Key: HIVE-3593 URL: https://issues.apache.org/jira/browse/HIVE-3593 Project: Hive Issue Type: Bug Components: Query Processor Affects Versions: 0.10.0 Reporter: Kevin Wilfong Assignee: Kevin Wilfong
The output files of a SMB join are prefixed by the big table's partition spec that was used to create them. The length of the bucket number portion of the file name is updated to be the same length as the length of the task ID. Since the task ID is the name of the file, this means that if the output of a SMB join is used as the big table of another SMB join, the output files will increase by the size of the original partition spec. Compound this and the file size can grow indefinitely. -- This message is automatically generated by JIRA.
