Jonathan Eagles commented on TEZ-2205:
--------------------------------------

This seems like a patch that will get the conversation going for what to do for 
this jira. [~rohini], can you comment from a pig perspective. Essentially, we 
are deeming it illegal to specify ATSHistoryLogger when timeline service is 
disabled. This approach gives clients the control of which history logger to 
use but leaves the yarn-timeline-service.enabled a flag that describes a 
feature that is available on the cluster.

> 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.
