View queues from YARN

In an EGO-YARN environment, the YARN GUI is integrated with the cluster management console, enabling you to access the YARN GUI from within the cluster management console. For enhanced usability, when you access the YARN scheduler page from the cluster management console, the application queues are organized as lists, rather than in tree structure.

Before you begin

  1. Ensure that the $EGO_CONFDIR/wsm.conf file includes the correct settings:
    1. Add the YARN_ENABLE=true setting to the file.
    2. Save your changes.
    3. Restart the WEBGUI service:
      egosh service stop WEBGUI
egosh service start WEBGUI
  2. Ensure that the name of the host on which the YARN GUI runs can be resolved by the host on which the client browser runs.

Procedure

Tip: Use the GUI action buttons to navigate back and forth between pages, not the browser back and next buttons. For example, when you select Integration > YARN > Tools > link, and then use the browser's back button, you return to the Cluster page, not the Tools page.

  1. From the cluster management console Dashboard, select Integration > YARN.
    The YARN Application Queues page displays.
    Note: The YARN GUI might report an HTTP ERROR 404 error while the EGOYARN service is restarting. To resolve this issue, refresh the page after the EGOYARN service is started.
  2. Expand the queue you want to view.

    A list of attributes for the particular queue displays.

    Note: After you submit workload in your EGO-YARN environment and refer back to the applications page, any History links under the Tracking UI column do not work until you start the job history server. Refer to your YARN documentation on how to start your job history server.
