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.

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 ?

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:
Error in the cloudera-scm-agent
