GitHub user beyond1920 opened a pull request: https://github.com/apache/flink/pull/3559 [flink-6037] [Table API & SQL]hotfix: metadata provider didn't work in SQL This pr aims to fix a bug referenced by https://issues.apache.org/jira/browse/FLINK-6037. After using the right MetadataProvider, org.apache.flink.table.ExpressionReductionTest.testReduceCalcExpressionForBatchSQL test cannot pass because the optimized plan is changed (The problem is referenced by https://issues.apache.org/jira/browse/FLINK-6067 which would be fixed in another pr). I simply changed test sql to make it pass in this pr.
