             Summary: 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: 3.1.5
            Reporter: Peter Szucs
            Assignee: Peter Szucs


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
