??The decimal result is incorrectly enlarged by 100 times??
Hi , I have came across a problem about correctness of spark decimal, and I have researched for it a few days. This problem is very curious. My spark version is spark 2.3.1 I have a sql like this: Create table table_S stored as orc as Select a*b*c from table_a Union all Select d from table_B Union all Select e from table_C Column a b c are all decimal(38,4) Column d is also decimal(38,4) Column e is also decimal(38,4) The result of this sql is wrong ,The result is 100 times greater than the correct value. The weird thing is ??If I delete ??create table?? clause ?? the result is correct. And I change the order of union , the result is also correct. E.g Create table table_S stored as orc as Select d from table_B Union all Select a*b*c from table_a Union all Select e from table_C Besides , spark 2.3.2 can gave correct result in this case. But I checked all the patch of 2.3.2, can not find which patch solve this problem. Can anyone gave some Help? Has anyone encountered the same problem??
