Summary: Checking data types when resolving types
Key: SPARK-6064
URL: https://issues.apache.org/jira/browse/SPARK-6064
Project: Spark
Issue Type: Improvement
Affects Versions: 1.3.0

In catalyst/expressions/arithmetic.scala and
catalyst/expressions/predicates.scala, many arithmetic/predicate requires the
operands to be of certain numeric type.
These type checking codes should be done when we are resolving the expressions.
