Muhammad Imran Tariq commented on FLINK-8008:
---------------------------------------------

I am using POJO way to read CSV file. Say a csv file have 2 columns.
ID - Integer | AGE - Double
When a csv file is read, DataSet will make id first column but PojoTypeInfo 
read fields in sorted way and place 'age' column at 0 index. So Double datatype 
is being applied to ID column. That's why I don't want to sort fields.

> PojoTypeInfo should sort fields fields based on boolean
