---------------------------
Issue Type: New Feature (was: Task)
> Re-implementation for some data types of Parquet in HAWQ
> --------------------------------------------------------
>
> Key: HAWQ-831
> URL: https://issues.apache.org/jira/browse/HAWQ-831
> Project: Apache HAWQ
> Issue Type: New Feature
> Components: Storage
> Reporter: Lili Ma
> Assignee: Lei Chang
>
> Re-implement some HAWQ data type mapping to Parquet, so that HAWQ can be
> compatible with Hive.
> 1. Currently HAWQ converts data type decimal to byte array, we can modify it
> to fixed length byte array, so that HAWQ can be compatible with Hive.
> 2. HAWQ itself can convert the data type char to int32 instead of byte array,
> so that the space for char storage can be saved.
> 3. To be compatible with Hive, HAWQ can change its type mapping for decimal
> to int96, but this need discussion.
