Ignite：无法运行在本地减少查询

Question

点燃version:2.7.0

以下是我使用的表达方式：

SELECT
    CASE WHEN YEAR(A1) = 2016 THEN SUM(A2) END 
FROM 
    table1

我犯了这样一个错误：

org.jkiss.dbeaver.model.sql.DBSQLException: SQL 错误 [1] [50000]: javax.cache.CacheException: Failed to run reduce query locally.

我在其他数据库中尝试了相同的 SQL，例如 MySQL，它成功了。

在 Oracle 中，我必须在 GROUP BY 子句中添加 A1。

然后，我尝试添加GROUP BY子句SQL.Oracle可以执行，但是Ignite还是returns同样的错误。

其实我也不知道哪里出错了

好像不喜欢CASE语句里面的SUM。不过，这有效：

select sum(case when a1 = 2016 then a2 end) from table1;

我不熟悉 SQL 规范，所以我不确定这是否是一个错误，但显然它可以处理更好的错误消息。
