okumin opened a new pull request #1873: URL: https://github.com/apache/hive/pull/1873
### What changes were proposed in this pull request? Build correct dependencies among CTEs in order to prevent wrong results. ### Why are the changes needed? A Hive query with `hive.optimize.cte.materialize.threshold` can return wrong results when it has complex CTEs. The issue can happen when multistage CTEs have dependencies and SemanticAnalyzer fails to link their tasks. https://issues.apache.org/jira/browse/HIVE-24606 ### Does this PR introduce _any_ user-facing change? No. Just a bug fix. ### How was this patch tested? This PR adds three test cases. All fail when using the latest revision(`58552a0c6b42988efb5160b045a3bf985477f117`). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
