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

             Summary: Query containing set operations (UNION/MINUS/INTERSECT) would cause
infinite loop in materialization substitution
                 Key: CALCITE-1688
                 URL: https://issues.apache.org/jira/browse/CALCITE-1688
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.11.0
            Reporter: Maryann Xue
            Assignee: Maryann Xue
            Priority: Minor


Example: {{select a from t1 union all select a from t2}} where materialized views are defined
on t1 and/or t2.
This is because MutableMultiRel, being super class of MutableSetOp, did not set "parent" and
"ordinal" for its input rels.
