             Summary: Failed to get value by int key from map nested into struct
                 Key: DRILL-7387
                 URL: https://issues.apache.org/jira/browse/DRILL-7387

Such test method in TestHiveStructs.java:

{code:java}
  @Test
  public void structWithMapByIntKey() throws Exception {
    testBuilder()
        .sqlQuery("SELECT rid, t.str_map.m[1] bk FROM hive.struct_tbl_p t")
        .unOrdered()
        .baselineColumns("rid", "bk")
        .baselineValues(1, 0)
        .baselineValues(2, 3)
        .baselineValues(3, 4)
        .go();
  }
{code}

is failing with exception:
