---------------------------------------
Summary: Provide an option in months_between UDF to disable
rounding-off
Key: HIVE-15511
URL: https://issues.apache.org/jira/browse/HIVE-15511
Project: Hive
Issue Type: Improvement
Reporter: Rajesh Balamohan
Priority: Minor
Rounding off was added in {{GenericUDFMonthsBetween}} so that it can be
compatible with systems like oracle. However, there are places where rounding
off is not needed.
E.g "CAST(MONTHS_BETWEEN(l_shipdate, l_commitdate) / 12 AS INT)" may not need
rounding off via BigDecimal which is compute intensive.
