Summary: Capture if a rule mutated the plan. Key: HIVE-12356 URL: https://issues.apache.org/jira/browse/HIVE-12356 Project: Hive Issue Type: Bug Affects Versions: 1.2.0 Reporter: Laljo John Pullokkaran Assignee: Laljo John Pullokkaran Currently Hive Optimizer doesn't capture if a rule mutated the plan. This info could be useful in: 1. determining if a subsequent optimization rule needs to be run or not (Ex if Constant propagation didn't mutate plan, then don't run subsequent PPD) 2. Explain can contain info about which optimizations are applied effectively on the query. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
