Xuefu Zhang commented on HIVE-6367:
-----------------------------------
Parquet doesn't have native decimal type. However, it's possible to support
Hive decimal data by serializing it into one of Parquet supported data type
such as binary. This is the approach that's going to move forward. Comments and
feedback are greatly appreciated.
> Implement Decimal in ParquetSerde
> ---------------------------------
>
> Key: HIVE-6367
> URL: https://issues.apache.org/jira/browse/HIVE-6367
> Project: Hive
> Issue Type: Task
> Reporter: Brock Noland
>
> Some code in the Parquet Serde deals with decimal and other does not. For
> example in ETypeConverter we convert Decimal to double (which is invalid)
> whereas in DataWritableWriter and other locations we throw an exception if
> decimal is used.
> This JIRA is to implement decimal support.
