Subject [jira] [Commented] (HIVE-14003) queries running against llap hang at times - preemption issues

    [ https://issues.apache.org/jira/browse/HIVE-14003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15335050#comment-15335050

Siddharth Seth commented on HIVE-14003:
---------------------------------------

Which ones specifically ?
My intent was to fix the rest of the TODOs left in the code as follow ups (after getting more
clarity, and some more support from Tez). Fix one known problem for now. Create new jiras
to fix others.

> The preemption logic in the Hive processor needs some more work. There are definitely
windows where the abort flag is completely dropped within the Hive processor.
