----------------------------------
Summary: Parse number as decimal
Key: SPARK-12848
URL: https://issues.apache.org/jira/browse/SPARK-12848
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Davies Liu
Right now, Hive parser will parse 1.23 as double, when it's used with decimal
columns, you will turn the decimal into double, lose the precision.
We should follow most database had done, parse 1.23 as double, it will be
converted into double when used with double.
