Subject [jira] [Created] (AMBARI-8888) Heartbeat lost messages in ambari log after host is decommissioned, deleted and perminently powered off

Alejandro Fernandez created AMBARI-8888:
-------------------------------------------

             Summary: Heartbeat lost messages in ambari log after host is decommissioned,
deleted and perminently powered off 
                 Key: AMBARI-8888
                 URL: https://issues.apache.org/jira/browse/AMBARI-8888
             Project: Ambari
          Issue Type: Story
          Components: ambari-server
    Affects Versions: 1.6.1
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.0.0


Repro Steps:
* Decommission a host
* Delete it from the cluster
* Poweroff the host
* Ambari still shows that heartbeats are lost from the host

[root@ambari hdp]# tail -f /var/log/ambari-server/ambari-server.log | grep "Heartbeat lost"

11:08:33,523 WARN [Thread-1] HeartbeatMonitor:126 - Heartbeat lost from host rm.lab 


Lab system running CentOS 6 with Ambari 1.6.1 on HDP 2.1.5 
[root@ambari ~]# rpm -qa | grep ambari-server 
ambari-server-1.6.1-98.noarch 

Looks like the HeartbeatMonitor thread looks up all hosts, as opposed to only the hosts associated
with the current cluster.
This does not impact the cluster itself, but does make the logs seem misleading.
