If you no longer require a cluster, you can release the cluster to delete the namespace that corresponds to the cluster and all software services that are deployed in the namespace. However, no physical resource is released after you release the cluster. This topic describes how to release a cluster.

Prerequisites

The cluster you want to release is in the Initializing, Running, or Idle state.

Procedure

  1. Log on to the EMR console.
  2. On the EMR on ACK page, find the cluster that you want to release and click Release in the Actions column.
  3. In the message that appears, click OK.
