hi,
we are getting the same issue in hive 1.2.1.
My tables is orc table and partitioned. calculating sum on a double field is
not giving accurate value.
expected value is 2.7115388423211*4*E14 but sum value comes as
2.7115388423211*378*E14
instead 114 it comes as 11378.
I do not see any round off issue also, I have tried by typecasting it to
decimal prior calculating sum. but the getting incorrect result.
is this issue still exist in 1.2.1

We are using hive 1.2.1 and facing the same issue.
Is this bug occuring in hive 2.0 also?

We are using hive 1.2.1 and facing the same issue. I feel this is related to
vectorisation. If I disable vectorization, I get the exact sum on a double
column.
Is this bug occuring in hive 2.0 also?
