--------------------------------------
Could you please take a look at https://github.com/apache/calcite/pull/398,
[~julianhyde]? This is the issue causing one of the hanging tests in
Calcite-Phoenix (cc [~rajeshbabu]).
> 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.
