[ https://issues.jboss.org/browse/TEIID-4875?page=com.atlassian.jira.plugin... ] Steven Hawkins updated TEIID-4875: ---------------------------------- Description: 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 With capabilities that disable join pushdown will fail with an assertionerror that a staged grouping symbol cannot be found during the initialization of the parent join node. java.lang.AssertionError: ASSERTION FAILED: expected reference to be not null at org.teiid.core.util.Assertion.failed(Assertion.java:73) at org.teiid.core.util.Assertion.isNotNull(Assertion.java:100) at org.teiid.core.util.Assertion.isNotNull(Assertion.java:92) at org.teiid.query.processor.relational.RelationalNode.getProjectionIndexes(RelationalNode.java:367) at org.teiid.query.processor.relational.JoinNode.initialize(JoinNode.java:133) at org.teiid.query.processor.relational.RelationalPlan.connectExternal(RelationalPlan.java:96) at org.teiid.query.processor.relational.RelationalPlan.connectExternal(RelationalPlan.java:102) at org.teiid.query.processor.relational.RelationalPlan.connectExternal(RelationalPlan.java:102) at org.teiid.query.processor.relational.RelationalPlan.initialize(RelationalPlan.java:91) at org.teiid.query.processor.QueryProcessor.init(QueryProcessor.java:226) at org.teiid.query.processor.QueryProcessor.nextBatchDirect(QueryProcessor.java:138) at org.teiid.query.processor.QueryProcessor.nextBatch(QueryProcessor.java:114) at org.teiid.query.processor.BatchCollector.collectTuples(BatchCollector.java:164) at org.teiid.query.processor.BatchCollector.collectTuples(BatchCollector.java:146) was: 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).
