Are you using default "Tez" view instance? Or are you creating a new Tez View instance?

Can you please share the screenshot of your Tez View configuration properties?

Ambari UI --> admin --> Manage Ambari --> Views --> Tez --> <Your Instance Name> (screenshot details)

- If you are using Tez View "Cluster Configuration" option as "custom" then you will have to provide the "YARN Timeline Server URL" and "YARN ResourceManager URL" properties.

1. Do you see any response from the following URL:

  http://<${ATS_HOSTNAME}:${ATS_PORT}/ws/v1/timeline/TEZ_DAG_ID?limit=1

2. Do you have YARN ACLs is enabled ?

3. Do you have the following settings in your "yarn-site.xml" ?

  "yarn.timeline-service.enabled"
  "yarn.timeline-service.webapp.address"   this  Value must be the IP:PORT on which timeline server is running

4. Do you see the complete error stack trace in the ambari-server log? Can you please share the log.

5. Also please check the ATS log to see if there is any error.

6. Do you have ResourceManager HA enabled?

But from your above reply i got a temporary solution. I created a new Instance of TEZ-View and its working. But the all my last query DAG are not imported in this new view.

Any suggestions???

Do you have a Kerberzed environment ?

If yes then in order to see any DAG information please do the following in your Yarn config:

yarn.admin.acl = yarn,dr.who,admin
yarn.acl.enable=false

Also check if your "tez-site.xml" file has the following property set properly ?

tez.am.view-acls=*

.

No! I do not have a Kerberzed environment, then what step should be taken.

And the tez-site.xml has following entry:

<property>

<name>tez.am.view-acls</name>

<value>*</value>

</property>
