> Updates to work on a secure cluster with HA ResourceManager
> -----------------------------------------------------------
>
> Key: TWILL-119
> URL: https://issues.apache.org/jira/browse/TWILL-119
> Project: Apache Twill
> Issue Type: Improvement
> Components: yarn
> Reporter: Albert Shau
> Assignee: Terence Yim
> Fix For: 0.11.0
>
>
> I have not tried it yet, but it seems like we may need some extra work for
> Twill to run on a secure cluster that uses HA ResourceManager. The YarnUtils
> class gets the socket addr for the RM using YarnConfiguration.RM_ADDRESS, but
> in HA mode the conf contains YarnConfiguration.RM_HA_IDS, with each id having
> a corresponding hostname setting.
