> Project: Calcite
> Issue Type: Bug

> Reporter: Anton Haidai

> Priority: Major
> Labels: pull-request-available

> *Materialized views enabled:*
> # {{select avg(grade), count\(*), max(grade), sum(grade), min(grade), team
> from students group by team}}
> # {{select avg(grade), count\(*), max(grade), sum(grade), min(grade), team,
> faculty from students group by faculty, team}},
> *Query:*
> # {{select count\(*), team from students group by team}}
> *Error* (stacktrace is obtained using the current *master* branch:

> Reproducible only if both Materialization views listed are enabled: any
> single one of these two could be successfully used with the query without any
> errors. Looks like is is reproducible when AbstractMaterializedViewRule is
> trying to rewrite one materialized view using the another materialized view.
> Currently, I'm trying to reproduce the issue in "MaterializationTest":
> without a success so far, I'll update the ticket if I'll find a working way
> to reproduce the issue in the test will be discovered.
