[jira] [Updated] (HIVE-17297) allow AM to use LLAP guaranteed tasks

     [ https://issues.apache.org/jira/browse/HIVE-17297?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sergey Shelukhin updated HIVE-17297:
------------------------------------
    Attachment: HIVE-17297.patch

A WIP patch based on HIVE-17256.
This is missing 3 things
- code to take ducks away from low pri tasks when scheduling a previously delayed high pri - I think I'd add this where a TODO now is upon further code reading just now
- code to propagate duck info back in the heartbeat; this is only needed to resolve the common rare scenario of sending a request but not receiving a response after success, and will come after heartbeat is made protobuf, ideally.
- tests :)
