[jira] [Created] (SPARK-21726) Check for structural integrity of the plan in QO in test mode

Reynold Xin created SPARK-21726:
-----------------------------------

             Summary: Check for structural integrity of the plan in QO in test mode
                 Key: SPARK-21726
                 URL: https://issues.apache.org/jira/browse/SPARK-21726
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Reynold Xin


Right now we don't have any checks in the optimizer to check for the structural integrity of the plan (e.g. resolved). It would be great if in test mode, we can check whether a plan is still resolved after the execution of each rule, so we can catch rules that return invalid plans.
