Updated at: Apr 28, 2020 GMT+08:00


The Storm web UI provides a graphical interface for using Storm. Only streaming clusters with Kerberos authentication enabled support this function.


  • The password of user admin has been obtained. The admin password is specified by the user when the MRS cluster is created.
  • If a user other than admin is used to access the Storm web UI, the user must be added to the storm or stormadmin user group.

    • If the Components tab is not displayed on the cluster details page, complete IAM user synchronization first. (On the Dashboard tab page of the cluster details page, click on the right side of IAM User Sync to synchronize IAM users.)
    • For MRS 1.8.10 or earlier, log in to MRS Manager. For details, see Accessing MRS Manager. Then, choose Services.

  2. Choose Storm. In Storm Web UI of Storm Summary, click any UI link to access the Storm web UI.

    When accessing the Storm web UI for the first time, you must add the address to the trusted site list.

    • Topology summary
    • Supervisor summary
    • Nimbus configurations
