View the status, resource usage, and configuration details of your EMR on ACK clusters.
Prerequisites
Before you begin, ensure that you have:
An EMR on ACK cluster. See Quick Start.
View the cluster list
Log on to the EMR on ACK console.
On the EMR on ACK page, view the cluster list.
Parameter Description Cluster ID/Name The ID and name of the cluster. Cluster Type The type of the cluster. Status The current lifecycle state of the cluster. See Cluster status reference. Cluster Resource Usage The CPU and memory usage of the cluster. To view per-component resource consumption, go to the Container Service for Kubernetes (ACK) console and check the resource usage of the corresponding pods. ACK Cluster The name of the ACK cluster. Namespace The namespace of the ACK cluster. Created At The time when the cluster was created. Actions Available operations: Configure — manage service configurations (see Manage configuration items); Release — release the cluster (see Release a cluster).
View cluster details
Log on to the EMR on ACK console.
On the EMR on ACK page, click the name of the cluster you want to inspect.
On the Cluster Details page, review the following information.
Parameter Description Cluster Name The name of the cluster created in EMR on ACK. Cluster ID The ID of the cluster created in EMR on ACK. ACK Cluster / Number Of Dedicated Nodes The name of the ACK cluster and the number of dedicated nodes. Namespace The namespace of the ACK cluster. OSS Bucket The bucket created in the Object Storage Service (OSS) console. Cluster Type The type of the cluster. Product Version The version information of the product. VPC The VPC information of the ACK cluster. Creation At The time when the cluster was created. Cluster Resource Usage The CPU and memory usage of the cluster. Maximum Resource The value of the ResourceQuota property for the ACK namespace that corresponds to the EMR cluster. Associated ShuffleService The association status of ShuffleService. Defaults to Not Associated. To associate a ShuffleService, click Associate. Data Lake Formation (DLF) The status of Data Lake Formation (DLF). Defaults to Disabled. To enable DLF, click Enable.
Cluster status reference
A cluster moves through a sequence of states during its lifecycle: it starts with Initializing, transitions to Running once ready, and eventually reaches Released after you release it. The following table describes each state.
| Status | Description |
|---|---|
| Initializing | The cluster is being created. |
| Running | The cluster is running normally. |
| Releasing | The cluster is being released. This state is entered after you click Release. |
| Released | The cluster has been released. Only cluster configuration is retained — job information is not saved. |
| Initialization Failed | The cluster failed to initialize. Basic configuration information (such as the cluster name and ID) is retained, but the cluster is unavailable. Configuration information is kept in the cluster list for seven days. |
| Release Failed | The cluster failed to be released. |
| Abnormal | The cluster is in an abnormal state. |
