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

             Summary: Sum of FlinkSql after two table union all.The value is too large.
                 Key: FLINK-11230
                 URL: https://issues.apache.org/jira/browse/FLINK-11230
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.7.0
            Reporter: jiwei


SELECT k AS KEY, SUM(p) AS pv
FROM (
 SELECT tumble_start(stime, INTERVAL '1' minute) AS k
 , COUNT(*) AS p
 FROM flink_test1
 GROUP BY tumble(stime, INTERVAL '1' minute)
 UNION ALL
 SELECT tumble_start(stime, INTERVAL '1' minute) AS k
 , COUNT(*) AS p
 FROM flink_test2
 GROUP BY tumble(stime, INTERVAL '1' minute)
) t
GROUP BY k

The Result of executing this sql is about 7000 per minute.But the result is 60 per minute for per table.Is there an error in your SQL statement?
