Configuring the Timeline Server to Use the Hive-on-Tez User Interface

This topic describes how to configure the timeline server to use the Hive-on-Tez user interface. This topic includes security configuration information.

When the timeline server is installed using the MapR Installer, the installer secures the timeline server automatically. When you install the timeline server manually, use these steps.

Note: This procedure assumes that you have previously configured the cluster using the configure.sh script.

Run configure.sh -R (on all Hive nodes), replacing <hostname> with the name of your timeline server node:
```
sudo /opt/mapr/server/configure.sh -R -TL <hostname>
```
Note: Make sure the hostname matches the CN in ssl_keystore for secure clusters. If not, all hive and yarn jobs fail. The hostname can be obtained using the $hostname -f command.

Running configure.sh -R configures the timeline server properties in /opt/mapr/hadoop/hadoop-2.7.0/etc/hadoop/yarn-site.xml for enhanced security.

To use the timeline server with Kerberos, you need to make additional entries to the /opt/mapr/hadoop/hadoop-2.7.0/etc/hadoop/yarn-site.xml file. Replace the following variables with real values:

MAPR_PRINCIPAL
PATH_TO_KEYTAB
HTTP_PRINCIPAL

<property>
  <name>yarn.timeline-service.principal</name>
  <value>MAPR_PRINCIPAL</value>
</property>
<property>
<name>yarn.timeline-service.keytab</name>
  <value>PATH_TO_KEYTAB</value>
</property>
<property>
  <name>yarn.timeline-service.http-authentication.kerberos.principal</name>
  <value>HTTP_PRINCIPAL</value>
</property>
<property>
 <name>yarn.timeline-service.http-authentication.kerberos.keytab</name>
 <value>PATH_TO_KEYTAB</value>
</property>

Restart the resource manager:

maprcli node services -name resourcemanager -action restart -nodes <hostname>
