Description

A bug can be reproduced by following step:
1. create a normal table and load data. For example
CREATE TABLE origin (key int, value string)
STORED AS carbondata

2. create an external table on table folder of "origin", and specify a new schema for it
CREATE EXTERNAL TABLE source (value string)
STORED AS carbondata
LOCATION 'path-to-origin'

3. query the external table and show, it should show only value column but currently it is showing key and value columns
