[jira] [Created] (CALCITE-4098) remove redundant code in "RelJson.toJson(RelDistribution)"

Jiatao Tao created CALCITE-4098:
-----------------------------------

             Summary: remove redundant code in "RelJson.toJson(RelDistribution)"
                 Key: CALCITE-4098
                 URL: https://issues.apache.org/jira/browse/CALCITE-4098
             Project: Calcite
          Issue Type: Improvement
          Components: core
            Reporter: Jiatao Tao
            Assignee: Jiatao Tao


RelDistribution#getKeys is annotated as nonnull, and must return "List<Integer>", so this code is unnecessary.

```

List<Object> keys = new ArrayList<>(relDistribution.getKeys().size()); 
 for (Integer key : relDistribution.getKeys()) { 
  keys.add(toJson(key)); 
 }

```
