[jira] [Updated] (HIVE-11272) LLAP: Execution order within LLAP daemons should consider query-specific priority assigned to fragments

["Siddharth Seth (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-11272?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Siddharth Seth updated HIVE-11272:
----------------------------------
    Attachment: HIVE-11272.1.txt

Patch to incorporate withinDagPriority into the scheduling decision.
This also changes to use self+upstream parallelism, instead of the static parallelism being used earlier.

[~prasanth_j] - please review. 

I'm going to follow up with another patch (separate jira) to make the scheduling policy pluggable via a classname, and shuffle tests around accordingly.

> It's currently looking at finishable state, start time and vertex parallelism. Vertex parallelism can be replaced by upstream parallelism as well.
