      Description

      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.

          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.

          FYI I converted this to a subtask of HIVE-6384 so I could link a single JIRA in the docs.
