Tez UI in HDP2.6

guillaume_roger — Tue, 03 Oct 2017 20:38:30 GMT

I am using hdp2.6 and would like to properly use Tez UI.

The tez view is available, if I go there I see queries, can click on a query id and follow to the dag ID, but I do not have all I expect.

DAG Details and DAG Counters look good.
Graphical View tells me: Data not available to display graphical view! No vertex data found in YARN Timeline Server.
All Vertices, All Tasks and All Task Attempts tell me: No records available!
Vertex Swimlane tells me: Data not available to display swimlane! No vertex data found in YARN Timeline Server.

I have seen the documentation relative to the manual install of HDP, saying to download a war file, but I do not believe this is what I should be doing here as I am using the ambari install from the cluster.

tez.tez-ui.history-url.base is http://$ambari_ip:8080/#/main/view/TEZ/tez_cluster_instance which is indeed the URL where I can reach the tez view.

Is there anything obvious I could have forgotten?

@Guillaume Roger

1. Please check if the parameter 'tez.am.view-acls' value is set to * (not blank)

Ambari UI -> MapReduce2 -> Configs -> Advanced tez-site -->  Add -->   tez.am.view-acls = *

2. Also please check if the value of "yarn.timeline-service.entity-group-fs-store.group-id-plugin-classes" in yarn-site.xml is set to "org.apache.tez.dag.history.logging.ats.TimelineCachePluginImpl"

3. Also for MR jobs please check if the property is set correctlt "mapreduce.job.acl-view-job"

Ambari UI -> MapReduce2 -> Configs -> Add -->  mapreduce.job.acl-view-job = *

4. Is this a kerberized Cluster?

1) was ok, 2) and 3) were not good and no it's not a kerberized cluster.

After the fixes you suggested it all seems to work as expected. Thanks a million!
