Configure the Timeline Server Store

You must configure the Timeline Server store to which the YARN ResourceManager publishes generic application-level data.

• yarn.timeline-service.store-class – The class name for the Timeline store.
  Example:

  <property>
   <description>Store class name for timeline store</description>
   <name>yarn.timeline-service.store-class</name>
   <value>org.apache.hadoop.yarn.server.timeline.LeveldbTimelineStore</value>
  </property>

• yarn.timeline-service.leveldb-timeline-store.path – The store file path and name for the Timeline Server LevelDB store (if the LevelDB store is used).
  Example:

  <property>
   <description>Store file name for leveldb timeline store</description>
   <name>yarn.timeline-service.leveldb-timeline-store.path</name>
   <value>${yarn.log.dir}/timeline</value>
  </property>

• yarn.timeline-service.ttl-enable – Enable age-off of timeline store data.
  Example:

  <property>
   <description>Enable age off of timeline store data.</description>
   <name>yarn.timeline-service.ttl-enable</name>
   <value>true</value>
  </property>

• yarn.timeline-service.ttl-ms – The Time-to-live for timeline store data (in milliseconds).
  Example:

  <property>
   <description>Time to live for timeline store data in milliseconds.</description>
   <name>yarn.timeline-service.ttl-ms</name>
   <value>604800000</value>
  </property>
