--------------------------------------------
Summary: Wrong scale used by ConvertDecimal64ToDecimal results in
incorrect results
Key: HIVE-20004
URL: https://issues.apache.org/jira/browse/HIVE-20004
Project: Hive
Issue Type: Bug
Affects Versions: 3.1.0, 3.0.1, 4.0.0
Reporter: Prasanth Jayachandran
ConvertDecimal64ToDecimal uses scale from output column vector which results in
incorrect results.
Input: decimal(8,1) Output: decimal(9,2)
Input value: 963.8 gets converted to 96.38 which is wrong. The scale should not
change this case (value should be 963.8 even after the conversion).
