Liang Chen commented on CARBONDATA-2318:
----------------------------------------

I tested it in sparkshell : 

Step1: ./bin/spark-shell --master local --jars ${carbon_jar} --driver-memory 4G

Step2: 

import org.apache.spark.sql.SparkSession
import org.apache.spark.sql.CarbonSession._
val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("/Users/apple/DEMO/presto_test/data","/Users/apple/DEMO/presto_test/metadata")

Step3: reuse the old carbondata

1) : copy all data "default/carbon_table/.." to new location : /Users/apple/DEMO/presto_test/data
2) : run carbon.sql("refresh table carbon_table")
