> In {{ParquetRecordReaderWrapper}} constructor, it create splits, set 
> projections and filters in conf, create task context, and then create Parquet 
> record reader. In this procedure, we could improve the logic of conf usage:
> 1. the clone of jobConf is not necessary. This could speed up getRecordReader 
> a little.
> 2. the updated jobConf is not passed to Parquet in one case.
