             Summary: Assertion when running Tpch 02 with optiq tracing enabled
                 Key: OPTIQ-415
                 URL: https://issues.apache.org/jira/browse/OPTIQ-415
             Project: Optiq
          Issue Type: Bug
    Affects Versions: 0.9.0-incubating
            Reporter: Aman Sinha
            Assignee: Julian Hyde


I was trying to determine why TPCH query 02 was taking a long time during planning.  I ran the following JUnit test in TpchTest: 
  @Test public void testQuery02Conversion() 

I enabled tracing in optiq by setting the -Doptiq.debug and -Djava.util.logging.config.file 

and encountered the following assert:
