Step 5, Installing Hadoop Parcel and Upgrading CDH Cluster, of BDA 5.x upgrade fails because an edge node with correct agent rpms fails to heartbeat into the cluster.
1. Navigating in Cloudera Manager: Hosts > All Hosts shows the edge node is not heartbeating.
2. Cloudera Manager reports:
This host has been out of contact with the Cloudera Manager Server for too
long. This host is not in contact with the Host Monitor.
3. The cloudera-scm-agent log, /var/log/cloudera-scm-agent/cloudera-scm-agent.log, on the edge node reports no errors.
4. But the cloudera-scm-server log, /var/log/cloudera-scm-server/cloudera-scm-server.log, on the Cloudera Manager host reports:
MainThread agent ERROR Heartbeating to <HOSTNAME3>.<DOMAIN>:7182 failed.
Traceback (most recent call last):
File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/cmf-5.16.1-py2.6.egg/cmf/agent.py", line 1442, in _send_heartbeat
response = self.requestor.request('heartbeat', heartbeat_data)
