             Summary: Planning issue with multiple aggregate decompositions through a join tree
                 Key: TEIID-4875
                 URL: https://issues.jboss.org/browse/TEIID-4875
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 9.3, 9.2.3


The logic for determining other symbols from aggregates will not work correctly when a staged grouping is initially pushed and another staged grouping is then pushed above a join that is above that location (typically due to join predicates that pull in other groups).

A query such as:

SELECT max(t3.e4), max(t2.e4) as s FROM pm1.g1 as t1, pm1.g2 as t2, pm1.g3 as t3, pm1.g4 as t4, pm2.g1 as t5 WHERE t1.e1 = t2.e1 and (t2.e2 = t3.e2 and t1.e3 || t2.e3 = t3.e3) and t3.e3 = t4.e3 and t4.e4 = t5.e4

Will fail with an assertionerror that a staged grouping symbol cannot be found during the initialization of the parent join node.
