Deploy Cloudera Manager with Rest Api template failed

Hi Abdulpasithali,

thank you for looking at my post.

The template you point me is totally different to the template we are using.
I try to deploy the template and got empty brackets returned. 

curl -X POST -H "Content-Type: application/json" -d @/tmp/cloudera_base_new.json http://admin:admin@9.152.187.116:7180/api/v54/cm/importClusterTemplate?addRepositories=true
{ }

You can find the template we using is to deploy a cloudera node here

Creating a Runtime Cluster Using a Cloudera Manager Template 

We export the configuration from an existing Cloudera Cluster, changed some values at the json file and try to deploy it on a new cluster.
But this import failed.

curl -X POST -H "Content-Type: application/json" -d @/tmp/cloudera_base.json http://admin:admin@my_cloudera_ip:7180/api/v54/cm/importClusterTemplate?addReposiies=true
{
"message" : "The following host(s) are not available: hdfs-44.vmlocal,hdfs-42.vmlocal,hdfs-43.vmlocal,hdfs-41.vmlocal."
}

Looking at the logfile at the cloudera node I see two java exceptions
