Peter Szucs updated YARN-11897:
-------------------------------
Affects Version/s: 3.5.0
(was: 3.1.5)
> NodeManager REST API backward compatibility with Jersey1
> --------------------------------------------------------
>
> Key: YARN-11897
> URL: https://issues.apache.org/jira/browse/YARN-11897
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: yarn
> Affects Versions: 3.5.0
> Reporter: Peter Szucs
> Assignee: Peter Szucs
> Priority: Major
>
> Jersey 2 upgrade broke NM REST API, so nodes applications page is not
> rendering in yarn UI v2 and also logs CLI cannot retrieve container logs.
> To fix this we need to:
> * introduce moxy in NM similar to YARN-11874
> * "/containers/\{containerid}/logs" endpoint returns a list, which will
> always be generated as a JSON array with Jersey 2. In Jersey 1 it returned a
> JSON object in case the list had a single element, and logs CLI expects a
> JSON object as well when calling this endpoint. That should be changed to
> keep backward compatibility. With returning a wrapper object instead of a
> list we could achieve the same behaviour.
> * Fix unit tests
