Subject [jira] [Commented] (HIVE-6367) Implement Decimal in ParquetSerde
Date Thu, 06 Feb 2014 15:32:10 GMT


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.

> 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.
