NamanRastogi opened a new pull request #3098: [CARBONDATA-3235] Fixed Alter Table Rename
URL: https://github.com/apache/carbondata/pull/3098
 
 
   Mixed a mistake in [PR-2996](https://github.com/apache/carbondata/pull/2996).
   The newTableIdentifier should have been newIdentifier
   
   Fixed negative scenario:
   
   **Alter Table Rename Table Fail**
   
   Problem: _When tabe rename is success in hive, for failed in carbon data store, it would throw exception, but would not go back and undo rename in hive._
   
   Solution: _A flag to keep check if hive rename has already executed, and of the code breaks after hive rename is done, go back and undo the hive rename._
