ajantha-bhat opened a new pull request #3089: [HOTFIX] presto carbon with hive connector doesn't work with Hadoop conf in cluster. 
URL: https://github.com/apache/carbondata/pull/3089
 
 
   **problem :** presto carbon with hive connector doesn't work with Hadoop conf in cluster. 
   
   **cause:**
   When presto queries are run in cluster, it fails with below message.
   **IllegalArgumentException java.net.UnknownHostException: hacluster**
   After integrating carbondata with hive connector, configuration from hdfsEnvironment is not set in thread local. Because of this, when FileFactory.getCarbonFile(path) is called, above exception was thrown.
   
   **solution**: set the configuration in thread local. so that file factory can get that conf.
