    [ https://issues.apache.org/jira/browse/YARN-2513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14638192#comment-14638192

Hitesh Shah commented on YARN-2513:
-----------------------------------

I am not sure if multiple uis work. 

Tried the following configs:

{code}
  <property>
    <name>yarn.timeline-service.ui-names</name>
    <value>tezui,tezui2</value>
  </property>

  <property>
    <name>yarn.timeline-service.ui-web-path.tezui</name>
    <value>/tezui</value>
  </property>

  <property>
    <name>yarn.timeline-service.ui-on-disk-path.tezui</name>
    <value>/install//tez/ui/</value>
  </property>


  <property>
    <name>yarn.timeline-service.ui-web-path.tezui2</name>
    <value>/tezui2</value>
  </property>

  <property>
    <name>yarn.timeline-service.ui-on-disk-path.tezui2</name>
    <value>/install/tez/tez-ui-0.8.0-SNAPSHOT.war</value>
  </property>
{code}

Logs:
