Description

timeline enabled flag check with in the TimelineCliemtImpl removed at YARN-2375
but ATSHook does not check timeline enabled.

ATSHook.java

        YarnConfiguration yarnConf = new YarnConfiguration();
        timelineClient = TimelineClient.createTimelineClient();
        timelineClient.init(yarnConf);
        timelineClient.start();

in the cluster that does not use timeline,
hive cli and hiveserver2 emit timeline retry log.
