+    <description>Whether to enable log aggregation. Log aggregation collects
+      each container's logs and moves these logs onto a file-system, for e.g.
+      HDFS, after the application completes. Users can configure the
+      "yarn.nodemanager.remote-app-log-dir" and
+      "yarn.nodemanager.remote-app-log-dir-suffix" properties to determine
+      where these logs are moved to. Users can access the logs via the
+      Application Timeline Server.
