> Path is converted to string in HiveContextAwareRecordReader to be stored in IOContext.inputPath, then in MapOperator normalizePath gets called on it which converts it back to Path. 
> Path creation is expensive, so it is better to use Path instead of string through the call stack.
> This is also a step towards HIVE-3616.
