So, we moved beyond this problem. Yarn configuration object needed to be
explicitly instantiated in the right spot even though yarn config files were
present on the classpath

Adding to Gopal, this configuration can be found as part of the Tez UI setup
which has more information regarding the configuration and enablement of the
Tez UI that is powered from the data stored in the Timeline store.

That's the YARN timeline configs. Not the Tez one.
<property>
<name>tez.history.logging. service.class</name>
<value>org.apache.tez.dag. history.logging.impl.
SimpleHistoryLoggingService</ value>
<!-- enable ATS
<value>org.apache.tez.dag. history.logging.ats. ATSHistoryLoggingService</
value>
-->
</property>
Those are the 2 configs to disable/enable ATS usage in Tez.
