Before you can begin using the management pack, you must create an adapter instance to identify the host from which the management pack will retrieve data.


  1. From the top navigation bar, select Administration. In the right panel, the Solutions view will be displayed.
  2. Select Apache Hadoop from the Solutions list on the right.
  3. Click the Configure configure_icon icon. The Manage Solution window will appear.
    Note: Click the Add add_icon icon above the Instance Namelist on the left to create multiple adapter instances.

  4. In the Manage Solution window, enter the following information:
    1. Instance Settings:

      • Display Name: Enter a name for this particular instance of the management pack.
      • Description: Optional field, but it can be helpful to describe multiple adapter instances of the management pack.
    2. Basic Settings:
      • NameNode Host: Enter the Hostname/IP address of your Hadoop NameNode JMX endpoint

      • ResourceManager Host: Enter the Hostname/IP address of your Hadoop ResourceManager JMX endpoint.

        Note: A credential is not used for the Management Pack for Apache Hadoop because JMX is read-only.
    3. Advanced Settings:
      • Collector: The collector you select determines which vRealize Operations Manager collector is used to manage the adapter processes. Default Collector/Group is automatically selected. Click the drop-down menu if you want to run the collection on a different node.
      • NameNode Port: Enter the port associated with your NameNode JMX endpoint (default is 50070).
      • ResourceManager Port: Enter the port associated with your ResourceManager JMX endpoint (default is 8088).

      • Collection Mode: Select your desired collection mode: Standard (collects everything) or Light (collects top-level NameNode and ResourceManager resources only).

        Note: In Light collection mode the management pack connects to top-level NameNode and ResourceManager resources only; however, it still provides select alerting for DataNode and NodeManager resources. Use of Light mode may help address performance problems by reducing the number of metric calls.
      • Timeout (seconds): Specify the timeout value for each HTTP call; default value is 5 seconds.
      • Max Threads: Specify the maximum number of threads to use during collection; field requires a minimum of 1 thread.
      • Dead Node Delete Age (Hours): Enter the number of hours to keep nodes that are determined to be dead/unreachable before setting them to notExisting. The default value is 0, which never sets dead nodes to notExisting.
      • Support Autodiscovery: Default setting is True, which enables the adapter instance to create resources for you. This should not be set to False.
  5. Click Test Connection to test the configured connection information.
  6. Click Save Settings and Close to save your adapter instance.
