    E-MapReduce:Component deployment information

    Last Updated:Aug 20, 2026

    In E-MapReduce, the service components deployed on cluster nodes vary by cluster version. For example, the NameNode component for HDFS is deployed on the master node. This topic explains how to view the deployment information for service components on each node.

    Procedure

    1. Go to the Services page of your cluster.

      1. Log on to the E-MapReduce console.

      2. In the top navigation bar, select the appropriate region and resource group.

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

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

    3. On the Status tab, view the deployment information for the service in the Components section.

      The following table lists the components that are deployed for each service in an EMR V5.15.1 cluster.
