> Components: storm-server
> Affects Versions: 2.1.0
> Reporter: Bipin Prasad

> Since metrics consumers are a system component and dynamically adding them should be possible with simple configuration change _topology.metrics.consumer.register_. Currently the _computeExecutors_ or more precisely - _StormCommon#startTaskInfo_ which evaluates this variable is only invoked during _startTopology_ , the rebalance functionality is not starting newer tasks.
> We need to ensure rebalance recalculates the idToExecutors again - hopefully only adding new tasks for added executors without removing old ids.
