Subject [jira] [Commented] (YARN-7939) Yarn Service Upgrade: add support to upgrade a component instance
Date Fri, 13 Apr 2018 01:03:00 GMT

Chandni Singh commented on YARN-7939:

[~eyang] The container may have failed which is why you see this exception. I will add a fix
that AM is able to container failures when its upgrading. For 3.1.1 we are targeting upgrades
of non-docker services only.

> Yarn core supports in-place upgrade of containers. A yarn service can leverage that to
provide in-place upgrade of component instances. Please see YARN-7512 for details.
> Will add support to upgrade a single component instance first and then iteratively add other
APIs and features.
