Prasanth J created HIVE-6956: -------------------------------- Summary: Duplicate partitioning column for union when dynamic partition sort optimization is enabled Key: HIVE-6956 URL: https://issues.apache.org/jira/browse/HIVE-6956 Project: Hive Issue Type: Bug Affects Versions: 0.13.0, 0.14.0 Reporter: Prasanth J Assignee: Prasanth J
HIVE-6455 optimization uses PreOrder graph walker resulting in double invocation of SortedDynPartitionOptimizer(). Because of this there are duplicate partitioning columns in RSOp for few test cases (union_remove_17.q and similar test cases..).. HIVE-6455 optimization does not actually need a PreOrder graph walker. The fix is to revert it to DefaultGraphWalker. -- This message was sent by Atlassian JIRA (v6.2#6252)
