Is this a secure or non-secure cluster? Secure clusters need some additional configs but usually the view should display back an error pointing to the problem.
The view errors are usually logged at debug level in the ambari-server ( think there is an open jira to fix this at some point ). Changing the log level may shed some light on the issue if there were errors. The common errors are usually: - misconfiguration of the RM or timeline hosts in the view configuration - failure to connect/read data from the above servers. Are you seeing the view with the table correctly displayed but having no data in the rows? 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. If you have specific issues with the Tez view, feel free to follow up at [email protected] thanks — Hitesh On Feb 12, 2016, at 7:14 AM, Harp, Michael <[email protected]> wrote: > Anyone have a technique for debugging view issues?
