[jira] [Created] (AMBARI-11570) Ambari agents stop heartbeating
after days of uptime
Robert Levas created AMBARI-11570:
-------------------------------------
Summary: Ambari agents stop heartbeating after days of uptime
Key: AMBARI-11570
URL: https://issues.apache.org/jira/browse/AMBARI-11570
Project: Ambari
Issue Type: Bug
Components: ambari-agent
Affects Versions: 2.1.0
Reporter: Robert Levas
Assignee: Robert Levas
Priority: Critical
Fix For: 2.1.0
If a cluster has been up for several days, Ambari complains that one or more of the agents have stopped heartbeating. This has been observed on Kerberized clusters, but may also occur on non-Kerberized clusters (not tested).
Looking at the ambari-agent log, it appear there may be an _open file_ issue

Restarting the ambari-agent reconnects with the server and the cluster becomes happy.
