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
