Review Comment:
   OK,eg: 
   1)When parquet real schema is (Day,day,user), if caseSensitive is 
true,selected schema is (Day,day,user) would be push down to read parquet 
success  When build ParquetFileReader,this sence is OK;
   2) When parquet real schema is (day,user),but user selected schema is 
(dAy,UseR),if caseSensitive is true it would not be push down to read parquet 
success;this sence should change caseSensitive to false to fit it. @danny0405
