--------------------------------

             Summary: Add plan integrity check
                 Key: IOTDB-987
                 URL: https://issues.apache.org/jira/browse/IOTDB-987
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: Core/Engine
            Reporter: Tian Jiang
            Assignee: Tian Jiang


As we enable users to create PhysicalPlans directly through Session API, some 
careless or even malicious users may construct erroneous plans, and such plans 
are not checked currently, which may interfere with IoTDB. Besides, users the 
construct such plans can merely get ambiguous error messages of the plans, 
because they trigger runtime exceptions like NPE or ArrayIndexOutOfBound.

We had better check the plans before they are executed.
