Junping Du commented on YARN-4601:
----------------------------------
I believe it is potentially to be critical in prospective of looking at YARN as
a competitive distributed OS to get more applications running on top of it.
Thoughts?
> HA as a general YARN service to highlighted container by application.

> Key: YARN-4601
> URL: https://issues.apache.org/jira/browse/YARN-4601
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: applications
> Reporter: Junping Du
> Assignee: Junping Du
> Priority: Critical
>
> For LRS (long running services) on YARN, get rid of single point failure for
> critical container failure may not be necessary. Some applications would like
> to build its own HA architecture. However, it would be ideal to provide some
> fundamental support to HA service in YARN, like: launching container marked
> with active/standby, monitor/trigger out failed over, provide end point for
> shring information between active/standby container, etc.
