----------------------------------
bq. i.e option 3's impl would be:
LGTM. For your reference, this is what we did in MR:
{code}
if (conf.getBoolean(MRJobConfig.MAPREDUCE_JOB_EMIT_TIMELINE_DATA,
MRJobConfig.DEFAULT_MAPREDUCE_JOB_EMIT_TIMELINE_DATA)) {
if (conf.getBoolean(YarnConfiguration.TIMELINE_SERVICE_ENABLED,
YarnConfiguration.DEFAULT_TIMELINE_SERVICE_ENABLED)) {
timelineClient = TimelineClient.createTimelineClient();
timelineClient.init(conf);
LOG.info("Timeline service is enabled");
LOG.info("Emitting job history data to the timeline server is enabled");
} else {
LOG.info("Timeline service is not enabled");
}
} else {
LOG.info("Emitting job history data to the timeline server is not
enabled");
}
{code}
And only when {{timelineClient != null}}, MR will publish the history info to
the timeline server.

> when set yarn.timeline-service.enabled=false, Tez still tries posting to ATS,
> but hits error as token is not found. Does not fail the job because of the
> fix to not fail job when there is error posting to ATS. But it should not be
> trying to post to ATS in the first place.
