Deploying Tez on Big Data Service Non-HA Clusters

Deploy Apache Tez on Big Data Service non-HA clusters.

Configure Tomcat:
1. Download Tomcat from following link: https://tomcat.apache.org/download-90.cgi.
2. Deploy Tez web server on the node where timeline server is running. The default timeline server node is mn1.
```
sudo tar xf /tmp/apache-tomcat-9.0.70.tar.gz -C /opt/
sudo ln -s /opt/apache-tomcat-9.0.70 /opt/tomcat
```
3. Start the Tomcat service:
  bin/startup.sh
4. Stop the Tomcat service:
  bin/shutdown.sh
Setup the Tez-UI.war file:
1. Download Tez-ui-0.10.1.war from https://repo1.maven.org/maven2/org/apache/tez/tez-ui/0.10.1/.
2. Unzip the war file and copy it to /opt/tomcat/webapps.
```
sudo cp /tmp/tez-ui-0.10.1.war /opt/tez/
sudo unzip /opt/tez/tez-ui-0.10.1.war -d /opt/tez/tez-ui
sudo cp -R /opt/tez/tez-ui /opt/tomcat/webapps/
```
3. Update /opt/tomcat/webapps/tez-ui/config/config.js with the hostname for both the timeline server and the resource manager:
```
ENV = {
  hosts: {
	timelineBaseUrl: 'http://144.25.40.156:8188',
	RMWebUrl: 'http://144.25.39.192:8088',
}
}; 
```

Update timeline and resourcemanager IPs in assets/tez-ui.js:

timeline":"localhost:8188","rm":"localhost:8088"}    should be updated with below details
timeline : 144.25.40.156:8188","rm":"144.25.39.192:8088"}

Kinit with ~/spnego.service.keytab by copying krb5.conf, spnego.service.keytab for UI access. Configure the timeline server and Tez from Ambari UI:

Access Apache Ambari.
From the side toolbar, under Services select Tez.
Select Configs.

On the Advanced tab, update the following:

Yarn-site.xml:

yarn.timeline-service.enabled = true
yarn.timeline-service.hostname = un0Node
yarn.timeline-service.http-cross-origin.enabled = true
yarn.resourcemanager.system-metrics-publisher.enabled = true

yarn.timeline-service.webapp.https address = un0.bmbdcsad1.bmbdcs.oraclevcn.com:8190
yarn.timeline-service.handler-thread-count = 24
yarn.timeline-service.generic-application-history.enabled = true
yarn.timeline-service.http-cross-origin.allowed-origins = *
yarn.timeline-service.hostname = <uno-hostname>

Tez-site.xml:

tez.history.logging.service.class : org.apache.tez.dag.history.logging.ats.ATSHistoryLoggingService
tez.tez-ui.history-url.base : http://144.25.40.156:8080/tez-ui-0.10.1/
yarn.timeline-service.enabled : true
tez.allow.disabled.timeline-domains : true
tez.am.history.logging.enabled : true
tez.dag.history.logging.enabled: true
tez.yarn.ats.enabled : true

Restart Yarn, Tez, and Hive from the Ambari Server.

Restart Tomcat.
