Description

Steps:

create carabondata and carbonindex file using SDK

place the files in a hdfs location

Read files using spark file format

create table schema15_int using carbon location 'hdfs://hacluster/user/rahul/map/mapschema15_int';

Select count from  schema15_int;

Actual Result:

Error: org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 24.0 failed 4 times, most recent failure: Lost task 0.3 in stage 24.0 (TID 34, BLR1000014238, executor 3): java.io.IOException: All the files doesn't have same schema. Unsupported operation on nonTransactional table. Check logs.
