    </property>

In yarn-site.xml:

    • Group: hadoop (or the relevant group used for admins)

    Example:

    <property>
     <description>DFS path to store active application’s timeline data</description>
     <name>yarn.timeline-service.entity-group-fs-store.active-dir</name>
     <value>/ats/active/</value>
    </property>
  • yarn.timeline-service.entity-group-fs-store.cleaner-interval-seconds

    Scan interval for ATS v1.5 entity group file system storage cleaner.This value controls how frequent the reader will scan the HDFS done directory for stale application data.

    Example:

    <property>
     <description>Scan interval for ATS v1.5 entity group file system storage cleaner.This value controls how frequent the reader will scan the HDFS done directory for stale application data. </description>

     <value>3600</value>
    </property>
  • yarn.timeline-service.entity-group-fs-store.done-dir

    </property>
  • yarn.timeline-service.entity-group-fs-store.group-id-plugin-classes
