             Summary: HOP_START() HOP_END() does not work when using HAVING clause with GROUP BY HOP window
                 Key: FLINK-7357
                 URL: https://issues.apache.org/jira/browse/FLINK-7357
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.3.1
            Reporter: Rong Rong


The following SQL does not compile:
{code:title=invalid_having_hop_start_sql}
SELECT 
  c AS k, 
  COUNT(a) AS v, 
  HOP_START(rowtime, INTERVAL '1' MINUTE, INTERVAL '1' MINUTE) AS windowStart, 
  HOP_END(rowtime, INTERVAL '1' MINUTE, INTERVAL '1' MINUTE) AS windowEnd 
FROM 
  T1 
GROUP BY 
  HOP(rowtime, INTERVAL '1' MINUTE, INTERVAL '1' MINUTE), 
  c 
HAVING 
  SUM(b) > 1
{code}
While individually keeping HAVING clause or HOP_START field compiles and runs without issue.
