---------------------------------
Summary: Remove unlimited DecimalType
Key: SPARK-9069
URL: https://issues.apache.org/jira/browse/SPARK-9069
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Davies Liu
Assignee: Davies Liu
Priority: Blocker
We should remove DecimalType.Unlimited, because BigDecimal does not really
support unlimited precision, especially for division.
We can have maximum precision as 38 (to match with Hive 0.13+). The default
precision and scale could be (38, 18).
