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 menu bar, select a region and resource group.

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

   4. Click the Auto Scaling tab.

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

   The following table describes the scaling activity statuses.

   Status	Description
   Successful	Nodes are added to or removed from the cluster based on the scaling rule. Note During a scale-out for a Hadoop cluster, abnormal ECS nodes are automatically released. Only healthy nodes are kept for subsequent computing. Datalake clusters now support custom best-effort delivery and provide a comprehensive alert mechanism. Select a scale-out delivery mechanism as needed. Upgrade as soon as possible.
   Failed	No nodes are added to or removed from the cluster based on the scaling rule.
   Running	The scaling activity is in progress.
   Request Denied	A scaling rule is rejected if its execution would cause the number of instances to go above the maximum limit or below the minimum limit. A rule is also rejected if it is triggered while the previous scaling activity is still in progress.
