-----------------------------------
Summary: Rebalance should re-computeExecutors so metrics consumers
can be added
Key: STORM-3574
URL: https://issues.apache.org/jira/browse/STORM-3574
Project: Apache Storm
Issue Type: Bug
Components: storm-server
Affects Versions: 2.1.0
Reporter: Bipin Prasad
Assignee: 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.
