  • Are you actively monitoring JMX values? Just because you have so much RAM doesn't mean your Java processes actually use it. Datanode doesn't require much RAM anyway – OneCricketeer Jul 25 '18 at 05:31
  • You can improve HDFS significantly by lowering your overall file counts. Don't store millions of tiny files; store tens of gigantic files – OneCricketeer Jul 25 '18 at 05:32
