E-MapReduce:View scaling records (Hadoop clusters only)

Procedure

1. Go to the Auto Scaling page.

   1. Log on to the EMR on ECS console.

   2. In the top navigation bar, select a region and resource group based on your requirements.

   3. On the EMR on ECS page, click the name of your target cluster.

   4. Click the Auto Scaling tab.

2. On the Auto Scaling page, click the Scaling Records tab.

   The following table describes the statuses of a scaling activity.

   Status	Description
   Successful Execution	The scaling rule adds nodes to or removes nodes from the cluster. Note During a scale-out operation for a Hadoop cluster, the system automatically releases unhealthy ECS nodes and retains only healthy nodes for computation. Datalake clusters now support custom best-effort delivery and provide a comprehensive alert mechanism. You can select a scale-out delivery mechanism based on your requirements. Upgrade your cluster to use this feature.
   Execution failed	The scaling rule does not add any nodes to or remove any nodes from the cluster.
   Running	The scaling activity is in progress.
   Request Denied	The system denies a request if it would cause the cluster's instance count to exceed the maximum number of instances or fall below the minimum number of instances. A request is also denied if triggered while another scaling activity is in progress.
