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

             Summary: Metadata provider for predicates pulls up expressions without references incorrectly
                 Key: CALCITE-1366
                 URL: https://issues.apache.org/jira/browse/CALCITE-1366
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.9.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


{code}
...
    for (RexNode r : inputInfo.pulledUpPredicates) {
      ImmutableBitSet rCols = RelOptUtil.InputFinder.bits(r);
      if (groupKeys.contains(rCols)) {
        r = r.accept(new RexPermuteInputsShuttle(m, input));
        aggPullUpPredicates.add(r);
      }
    }
...
{code}

The check does not take into account that _rCols_ might be empty, and then _r_ cannot be pulled up e.g. count(*).
