Re: ERROR MESSAGE:This host is not in contact with the Host Monitor.

[ Edited ]

I created a new ticket for this problem as a summury, but i can't find it , why?

 

I move it to here.

 

I want to add a host to existing cluster as a datanode.

But the host don't work fine as expected. 

1, I confirmed status of agent and it is working fine.

cloudera-scm-agent (pid  162575) is running...

2, I restarted the cluster and CDM , the problem can't be resolve.

3, I stopped agent and add the host and restart agent again ,  the problem can't be resolve also.

 

Looking forward to your response.

And please let me know if you want more info.

 

Thanks,

Wenjie

Re: ERROR MESSAGE:This host is not in contact with the Host Monitor.

We are facing the same issue. What steps did you follow to install the host again?

Re: ERROR MESSAGE:This host is not in contact with the Host Monitor.

Could you share any error logs or screenshot ? where are you facing the issue ? 

Were you able to see the CDH version in the Host summary ?

Re: ERROR MESSAGE:This host is not in contact with the Host Monitor.

Hi

 

Hi,

 

I removed 2 nodes from the cluster and tried to add them back from managed hosts and the download , distribute is successful but stuck at the activation.

But the 2 nodes got added to the cluster and show up in the hosts but CDH version is NONE.(Host in bad health)

 

Host Agent status:

This host is in contact with the Cloudera Manager Server. This host is not in contact with the Host Monitor.
 
Not able to run any services on these nodes and getting connection refusal to all ports except "7180"

 

Error in the cloudera-scm-agent

 

Caught unexpected exception in main loop.
