Liang-Chi Hsieh resolved SPARK-21990. ------------------------------------- Resolution: Not A Problem > QueryPlanConstraints misses some constraints that can be recursively inferred > ----------------------------------------------------------------------------- > > Key: SPARK-21990 > URL: https://issues.apache.org/jira/browse/SPARK-21990 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.2.0 > Reporter: Liang-Chi Hsieh > > When I inspected the latest change of SPARK-21979, I found we could miss few > constraints that can be recursively inferred. > E.g. consider constraints {{a === b && b === c && a === 1 && b === 5}}. > Currently we only infer {{a === c && b === 1 && c === 5}}, but {{c === 1}} > can be also inferred from newly inferred constraint {{a === c}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
