In ambari version 2.6, my centos service can connect to the external public
network. When I installed ambari, the following error message
!image-2023-10-23-17-27-29-741.png|width=615,height=133!
appeared when registering the agent node. I temporarily expanded the
hosts.public_host_name field in the pgsql database to character varying(30000)
and found that this field stored A very long html code,I checked the code for
registering the host in the agent and found that there is an IP address of
169.254.169.254. My host can work with this IP. After I changed this code to
the following form,
!image-2023-10-23-17-28-47-606.png|width=536,height=135!
change
!image-2023-10-23-17-29-31-124.png|width=562,height=135!
the host registration was normal after restarting ambari-agent. , there is no
error message in ambari-server. I feel this problem is a bug.
