+ <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.
