Jagadish updated SAMZA-1687:
----------------------------
Issue Type: Sub-task (was: Bug)
Parent: SAMZA-1484
> Prioritize preferred host requests over ANY-HOST requests
> ---------------------------------------------------------
>
> Key: SAMZA-1687
> URL: https://issues.apache.org/jira/browse/SAMZA-1687
> Project: Samza
> Issue Type: Sub-task
> Reporter: Jagadish
> Assignee: Jagadish
> Priority: Major
> Fix For: 0.14.1
>
>
> Yarn enforces these two checks:
> 1. ANY_HOST requests should always be made with relax-locality = true
> 2. A request with relax-locality = false should not be in the same priority
> as another with relax-locality = true
> Since the Samza AM makes preferred-host requests with relax-locality = false,
> it follows that ANY_HOST requests should specify a different priority-level.
> We can safely set priority of preferred-host requests to be higher than
> any-host requests since data-locality is critical.
