You can submit the Delete cluster job
to remove a cluster from the flexible management environment.
Before you begin
Start the job manager, the deployment manager, and the
nodes on which the cluster resides.
Each cluster that you want
to delete must be a managed resource of the job manager.
About this task
You can use the administrative console of the job manager
to delete a cluster from one or more managed nodes. From the job manager
console, choose the Delete cluster job, specify
job options, review the summary, and submit the job.
The job
stops the cluster, if it is running, and removes the cluster from
the flexible management environment and from the deployment manager
node.
Instead of using the job manager console, you can run
the deleteCluster job script in the AdministrativeJobs command group.
See the Administrative job types topic.
