PERFORMANCE: HDataType.getWritableComparableTypes() method can use the supplied key type rather than figuring it out using instanceof

                 Key: PIG-677
                 URL: https://issues.apache.org/jira/browse/PIG-677
             Project: Pig
          Issue Type: Improvement
    Affects Versions: types_branch
            Reporter: Pradeep Kamath
            Priority: Minor
             Fix For: types_branch


Currently HDataType.getWritableComparableTypes method gets the object for which a NullableXXX object needs to be returned and also the key type which indicates the data types of the incoming object. However by default the method calls DataType.findType on the incoming object which inturn does an instanceof with if-else to figure out the type. This can be avoided since the second argument, keyType, already has the type of the incoming object
