Matei Zaharia updated SPARK-3929:
---------------------------------
Description: Spark SQL should support fixed-precision decimals, which are
available in Hive 0.13 (see
https://cwiki.apache.org/confluence/download/attachments/27362075/Hive_Decimal_Precision_Scale_Support.pdf)
as well as in new versions of Parquet. This involves adding precision to the
decimal type and implementing various rules for math on it (see above).
