ModifyInstanceGroups modifies the number of nodes and configuration settings of an instance group. The input parameters include the new target instance count for the group and the instance group ID. The call will either succeed or fail atomically.

Example

Use a bare-bones client and the command you need to make an API call.

import { EMRClient, ModifyInstanceGroupsCommand } from "@aws-sdk/client-emr"; // ES Modules import
// const { EMRClient, ModifyInstanceGroupsCommand } = require("@aws-sdk/client-emr"); // CommonJS import
const client = new EMRClient(config);
const input = { // ModifyInstanceGroupsInput
  ClusterId: "STRING_VALUE",
  InstanceGroups: [ // InstanceGroupModifyConfigList
    { // InstanceGroupModifyConfig
      InstanceGroupId: "STRING_VALUE", // required
      InstanceCount: Number("int"),
      EC2InstanceIdsToTerminate: [ // EC2InstanceIdsToTerminateList
        "STRING_VALUE",
      ],
      ShrinkPolicy: { // ShrinkPolicy
        DecommissionTimeout: Number("int"),
        InstanceResizePolicy: { // InstanceResizePolicy
          InstancesToTerminate: [ // EC2InstanceIdsList
            "STRING_VALUE",
          ],
          InstancesToProtect: [
            "STRING_VALUE",
          ],
          InstanceTerminationTimeout: Number("int"),
        },
      },
      ReconfigurationType: "OVERWRITE" || "MERGE",
