I want to add a host to cluster as a datanode.
Now i can find the host in host list and adding the New Hosts to existing Cluster.
it looks it takes time because i began it 1hours ago but it is still running.
And i can find it in the cluster with new windows even the processing is running.
Bus Health test is bad.
"This host is in contact with the Cloudera Manager Server. This host is not in contact with the Host Monitor."
How can i investigate it ?
And i confirmed the log of host and found it.
Caught unexpected exception in main loop.
Traceback (most recent call last):
File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/cmf-5.10.0-py2.6.egg/cmf/agent.py", line 710, in __issue_heartbeat

assert response_data.get("cm_guid") is not None
Whats the status of cloudera-scm-server-db and cloudera-scm-server ?
Please share your Cloudera Manager Agent logs and Host monitor logs for more insight .
I restarted the agent in host.
But can't reslove it .
And i found i can't get the CDH version ("None") in the host list.
But existing datanode shows "CDH 5"
I restarted the CDM and HOST MONITOR, it still can't be resloved.
And i can't find CDH version in host list also for new host.
By the way , HOST MONITOR service and other datanode (existing) is working fine.
so i guess some setting in new host is not good.
