-------------------------------------------
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.
