KanakaKumar opened a new pull request #3198: [CARBONDATA-3369] Fix issues during concurrent execution of Create table If not exists
URL: https://github.com/apache/carbondata/pull/3198
 
 
   Create table if not exists has following problems if run concurrently from different drivers 
   
   1) Sometimes It fails with error "Table <db.table> already exists." 
   2) Create table failed driver still holds the table with wrong path or schema. Eventual operations refer the wrong path
   3) Stale path created during create table is not deleted for ever [After 1.5.0 version table will be created in a new folder using UUID if folder with table name already exists]
   
   This PR fixes above 3 issues.
