Hi all,


  when loading data from a csv file to carbondata table, we have 2 choices to mapping the columns from csv file to carbondata table:


  1. add columns' names at the start of the csv file
  2. declare the column mapping at the data loading script


  shall we add a feature which make an auto mapping in the order of the columns at the csv file and the carbondata table at default, so that users don't have to do the above jobs any more under most of the circumstance.
