Thanks for the tips,
This is non-secure cluster but also seeing with kerberos enabled. I did start ambari-server
with the debug flag but do not see any errors.
Yes, tez view displays correctly but show “No records available!". The api endpoint http://timelinehost:8188/ws/v1/timeline/TEZ_DAG_ID?limit=11
returns empty array;
	* "entities": [ ]


Acls are set to asterisk in tez config,*

Using identical blueprint to deploy with ambari- and Tez views are working. Issue with
Tez seems to have started with
I will keep digging.

Try the following call: http://timelinehost:8188/ws/v1/timeline/TEZ_DAG_ID?limit=11. If this
does not return any data, you will need to debug whether the tez jobs were configured to write
data to ATS. Additionally, if your cluster has acls enabled ( search for acls in tez-site.xml
), it might not be showing you data based on which user ran the job and if you are logged
in to ambari with a different user id.
