> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers
> Affects Versions: 0.14.0
> Reporter: Xuefu Zhang

>
> Because of storing decimal numbers as fixed length bytes, Parquet Serde pads
> leading zeros for decimal numbers that has less bytes representation. This
> works fine for positive decimals, but messes up with negative ones, for
> which, leading 1 bits are needed.
