             Summary: Add a mode in LlapDaemons where UGI instances are not created per executor
                 Key: HIVE-12622
                 URL: https://issues.apache.org/jira/browse/HIVE-12622
             Project: Hive
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


In most cases, the UGI can be re-used across different fragments - since the data is owned
by Hive. This can cut down the number of connections established to datanodes / the namenode.
