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

             Summary: No Checkpointing is done when Delay Operator is used 
along with Partitioned Operators.
                 Key: APEXCORE-654
                 URL: https://issues.apache.org/jira/browse/APEXCORE-654
             Project: Apache Apex Core
          Issue Type: Bug
    Affects Versions: 3.5.0
         Environment: Hadoop 2.7.2
Apache Apex 3.5.0
Apache Apex Malhar 3.6.0
            Reporter: Ambarish Pande
         Attachments: Delay Test DAG.png, Delay test no checkpointing.png

Checkpointing is not happening when DefaultDelayOperator is used in a DAG in 
which some upstream operators are Partitioned. I have attached screenshots of 
the application DAG and also stats showing that the checkpointing is not being 
done. 

When used without partitioning, I can see the operators being check-pointed 
properly.

Here is the link of the App source code and also the built apa file.
