ambari Datanode stale status

[#1]

I use ambair 2.0.1 with HDP 2.2.0 GA installed . but from yesterday I found there are lot's of stale status nodes from ambari UI.it's vary most of the time. is there any idea or workaround for this?

I've followed https://hortonworks.my.salesforce.com/articles/en_US/Issue/Ambari-keeps-showing-stale-alerts-There-a... .but the alert still there.
