URL: https://issues.apache.org/jira/browse/HIVE-3036
Project: Hive
Issue Type: New Feature
Components: Query Processor
Affects Versions: 0.8.1, 0.8.0, 0.7.1
Reporter: Anurag
Fix For: 0.10.0
hive has support for big int but people have use cases where they need decimal precision to a big value.
Values in question are like decimal(x,y).
for eg. decimal of form (17,6) which cannot be represented by float/double.

[jira] [Commented] (HIVE-3036) hive should support BigDecimal

Anurag Tangri commented on HIVE-3036:
-------------------------------------
Looked at some pig implementation where java's big decimal is not being used.
There is definitely a performance issue with java's big decimal but having this feature is important in lot of financial institutions who care about precision upto 8-12 places after decimal points.
They might not care right now about the performance hit vs having this in hive.
I suggest to include it in primitive types in hive along with other java types. And can start working on it.
Any thoughts anyone ?
Thanks,
Anurag Tangri
