             Summary: LLAP: memory.mode = none has NPE
                 Key: HIVE-14621
                 URL: https://issues.apache.org/jira/browse/HIVE-14621
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


When IO elevator is enabled, but cache and allocator are both disabled, NPEs happen. It's not really a recommended mode, but it's the only way to disable cache, so we probably need to fix it. I am probably also going to nuke the intermediate mode (allocator w/no cache) meanwhile cause it's pointless and just creates a zoo of configurations.
