             Summary: Strict & lenient Physical Plan checking
                 Key: APEXCORE-547
                 URL: https://issues.apache.org/jira/browse/APEXCORE-547
             Project: Apache Apex Core
          Issue Type: Improvement
            Reporter: Sandesh


This will need a bigger discussion, filing here so that it can be tracked.

Example:

Container max memory is set by yarn settings. So multiple operators in a 
container with the high memory requirement may not get the sufficient memory, 
as Apex just allocates the yarn allowed max memory and launches the 
application. 

Users should have a control saying don't launch the app if memory requirements 
are not set.
