Hi,
目前 Flink SQL 在插入数据到数据库时，要求 query 的 key 与结果表的 key 相同。这里 HBase 的 key 一直都是
rowkey，但是 query 的 key 丢失了（concat_ws 丢失了 key 属性），因此需要直接 group by
concat_ws(..)，才能获得 key 且对应上 HBase 的 rowkey。所以你的 query 需要改成这样：
insert into resume01
select age_name,ROW(age,mobile)
from (
select CONCAT_WS('_',age,name) as age_name,sum(cast(mobile as bigint))
as mobile
from source_resume group by CONCAT_WS('_',age,name)
) as tt
Best,
Jark
