-------------------------------------
Assignee: Thomas Graves
> Update YARN cluster manager For Stage Level Scheduling
> ------------------------------------------------------
>
> Key: SPARK-29149
> URL: https://issues.apache.org/jira/browse/SPARK-29149
> Project: Spark
> Issue Type: Story
> Components: YARN
> Affects Versions: 3.0.0
> Reporter: Thomas Graves
> Assignee: Thomas Graves
> Priority: Major
>
> For Stage Level Scheduling, we need to update the YARN allocator to handle
> requesting executors for multiple ResourceProfiles.
> * The container requests have to be updated to be based on a number of
> containers per ResourceProfile. This is a larger change then you might
> expect because on YARN you can’t ask for different container sizes within the
> same YARN container priority. So we will have to ask for containers at
> different priorities to be able to get different container sizes. Other YARN
> applications like Tez handle this now so it shouldn’t be a big deal just a
> matter of mapping stages to different priorities.
> * The allocation response from YARN has to match the containers to a
> resource profile.
> * We need to launch the container with additional parameters so the executor
> knows its resource profile to report back to the ExecutorMonitor.
