E-MapReduce:View the deployment information of service components

Procedure

1. Go to the Services tab.

   1. Log on to the EMR console. In the left-side navigation pane, click EMR on ECS.

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

   3. On the EMR on ECS page, find the desired cluster and click Services in the Actions column.

2. On the Services tab, find the desired service and click Status.

3. In the Components section of the Status tab, view the deployment information of the service components.

   The following table describes the deployment information of the service components that are deployed on an EMR cluster of V5.15.1.
