Subject Re: Question about yarn.timeline-service.enabled

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
thanks,Madhu

 We're in the process of setting up Tez UI, and nothing is being logged to timeline server
and we see "no records available" in tez ui
We already have the following config in tez-site.xml

Logging</description>    <name>tez.history.logging.service.class</name> 
  <value>org.apache.tez.dag.history.logging.ats.ATSHistoryLoggingService</value>

 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.

Cheers,
Gopal
