> Project: Hive
> Issue Type: Bug
> Components: Types
> Reporter: Krisztian Kasa
> Assignee: Krisztian Kasa
> Priority: Major
> Labels: pull-request-available
> Time Spent: 2h
> Remaining Estimate: 0h

> In some case Hive removes trailing zeros of constant decimal numbers
> {code}
> select cast(1.1 as decimal(22, 2))
> 1.1
> {code}
> In this case *WritableConstantHiveDecimalObjectInspector* is used and this
> object inspector takes it's wrapped HiveDecimal scale instead of the scale
> specified in the wrapped typeinfo:
> {code}
> this = {WritableConstantHiveDecimalObjectInspector@14415}
> value = {HiveDecimalWritable@14426} "1.1"
> typeInfo = {DecimalTypeInfo@14421} "decimal(22,2)"{code}
> However in case of an expression with an aggregate function
> *WritableHiveDecimalObjectInspector* is used
> {code}
> select cast(sum(1.1) as decimal(22, 2))
> 1.10
> {code}
> {code}
> o = {HiveDecimalWritable@16633} "1.1"
> oi = {WritableHiveDecimalObjectInspector@16634}
> typeInfo = {DecimalTypeInfo@16640} "decimal(22,2)"
> {code}
> Casting the expressions to string
> {code:java}
> select cast(cast(1.1 as decimal(22, 2)) as string), cast(cast(sum(1.1) as
> decimal(22, 2)) as string)
> 1.1 1.10
> {code}
