---------------------------------------
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.
