my question is, can we use only one storm ui for multiple nimbus?. because if nimbus is fail on the machine, the ui also getting error on the browser. even not a leader nimbus is changed as a leader (which is running on another machine )

instead of running storm ui for every nimbus running machine, can we set storm ui commonly for all the nimbus ? if can how to achieve

  1. Yes, you can deploy only one UI instance for the whole cluster no matter its size.
  2. If your cluster running more than 20+ supervisors host I would recommend spawning 3 instances of nimbus to resilience. From my real production practice, the number of nimbus instances should be odd (1-3-5) to remain quorum in case of unavailability (1 for 3, 2 for 5), but 3 is quite enough up to 100 supervisors.
  3. Same rule is for zookeeper instances (1-3-5).
