Description

Make sure the valueObj instance variable is always initialized. This change is neeeded when running a Hive query that uses the CombineHiveInputFormat and the first file in the combined split is empty. This can lead to a NullPointerException because the valueObj is null when the CombineHiveInputFormat calls the createValue method.
