Description

This boolean property enables age off (defaults to enabled):

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

This property is the length of time to wait before deleting entities, based on their key timestamp (defaults to 1 week):

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

This property controls how long the age off thread waits between deletion cycles (defaults to 5 minutes). It shouldn't need to be changed, but if deletion is taking too long for some reason, this value could be lowered so that it runs more frequently.

  <property>
    <description>Length of time to wait between deletion cycles of leveldb timeline store in milliseconds.</description>
    <name>yarn.timeline-service.leveldb-timeline-store.ttl-interval-ms</name>
    <value>300000</value>
  </property>
