["Zhijie Shen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-3287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14505910#comment-14505910 ] 

Zhijie Shen commented on YARN-3287:
-----------------------------------

It breaks the timeline access control of distributed shell. In distributed shell AM:

{code}
    if (conf.getBoolean(YarnConfiguration.TIMELINE_SERVICE_ENABLED,
      YarnConfiguration.DEFAULT_TIMELINE_SERVICE_ENABLED)) {
      // Creating the Timeline Client
      timelineClient = TimelineClient.createTimelineClient();
      timelineClient.init(conf);
      timelineClient.start();
    } else {
      timelineClient = null;
      LOG.warn("Timeline service is not enabled");
    }
{code}

{code}
      ugi.doAs(new PrivilegedExceptionAction<TimelinePutResponse>() {
        @Override
        public TimelinePutResponse run() throws Exception {
          return timelineClient.putEntities(entity);
        }
      });
{code}

This Jira changes the timeline client to get the right ugi at serviceInit, but DS AM still doesn't use submitter ugi to init timeline client, but use the ugi for each put entity call. It result in the wrong user of the put request.
