Sergey Shelukhin commented on HIVE-17256: ----------------------------------------- Yes, there needs to be a writeup for workload management (for which this is a building block). I think we'll do it after AM and HS2 patches are ready. > add a notion of a guaranteed task to LLAP > ----------------------------------------- > > Key: HIVE-17256 > URL: https://issues.apache.org/jira/browse/HIVE-17256 > Project: Hive > Issue Type: Bug > Reporter: Sergey Shelukhin > Assignee: Sergey Shelukhin > Fix For: 3.0.0 > > Attachments: HIVE-17256.01.patch, HIVE-17256.patch > > > Tasks are basically on two levels, guaranteed and speculative, with > speculative being the default. As long as noone uses the new flag, the tasks > behave the same. > All the tasks that do have the flag also behave the same with regard to each > other. > The difference is that a guaranteed task is always higher priority, and > preempts, a speculative task. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
