> use Path instead of String for IOContext.inputPath

>
> 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.
