    Description

      In DataWritableReadSupport.init(), the table schema is created and its string format is set in conf. When construct the ParquetRecordReaderWrapper , the schema is fetched from conf and parsed several times.

      We could remove these schema parsing, and improve the speed of getRecordReader a bit.
