Creating a Runtime Cluster Using a Cloudera Manager Template
You can create a new cluster by exporting a cluster
template from an existing cluster managed by Cloudera Manager. You can
then modify the template and use it to create new clusters with the same
configuration on a new set of hosts.
Duplicate clusters for use in developer, test, and production environments.
Quickly create a cluster for a specific workload.
Reproduce a production cluster for testing and debugging.
Follow these general steps and refer to the following tasks to create a template and
a new cluster:You can only import
a cluster template to create a new cluster that is running the same
version of Cloudera Runtime as the cluster from which the template was
exported.
Export the cluster configuration from the source cluster. The exported configuration is
a JSON file that details all of the configurations of the cluster. The JSON file includes
an instantiator section that contains some values you must provide before
creating the new cluster.
Set up the hosts for the new cluster by installing Cloudera Manager agents and the
JDK on all hosts. For secure clusters, also configure a Kerberos key distribution center
(KDC) in Cloudera Manager.
Create any local repositories required for the cluster.
See Step
1: Configure a Repository for Cloudera Manager.
Complete the instantiator section of the cluster configuration
JSON document to create a template.
