             Summary: LLAP: prep object registry for multi threading
                 Key: HIVE-9810
                 URL: https://issues.apache.org/jira/browse/HIVE-9810
             Project: Hive
          Issue Type: Sub-task
            Reporter: Gunther Hagleitner
            Assignee: Gunther Hagleitner


The object registry relies on the fact that only one thread at a time is active 
in a container. With llap that's not the case. There's multiple threads that 
will try to generate the same cache object at the time, etc.
