Can you please check your Yarn setting for the following properties
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 ?
Is it a kerberized environment?
The cluster is kerberoized. Our custom "ambari-qa" account is part of proxyusers groups and hosts.
yarn.acl.enable = true
yarn.admin.acl = yarn, dr.who, <our-custom-yarn-user>
Please suggest me do I need to modify anything
Can you put your user-id in yarn.admin.acl = user_id_name then restart the required services and try to restart the Tez View Instance.
