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

             Summary: Sql. Some queries exceptionally executed if some rules are disabled.
                 Key: IGNITE-18569
                 URL: https://issues.apache.org/jira/browse/IGNITE-18569
             Project: Ignite
          Issue Type: Bug
          Components: sql
    Affects Versions: 3.0.0-beta1
            Reporter: Evgeny Stanilovsky


Found that if only one aggregate rule *HashAggregateConverterRule.COLOCATED* become available (in practice it can win by summary weights), we obtain exception, like :

concrete this test can be found in */sqlite/aggregates/agg1.test*.
There are also numerous faled tests if only one aggregate rule become enabled.
