Hi [~Nicholas Niu] , what do you think about this issue? Is the worker group
shared across all the Raft clients or only for the between connections in a
single client?

> Components: Netty
> Reporter: Ivan Andika
> Assignee: Ivan Andika
> Priority: Minor
>
> When benchmarking Ozone streaming pipeline using `ozone freon ockg`, the
> benchmark would not end although all the keys have been written.
> Using Arthas, found that non-daemon threads like
> "NettyClientStreamRpc-workerGroup–thread1" are still running even after the
> benchmark has finished.
> It seems that when hdds.ratis.raft.netty.dataStream.client.worker-group.share
> is set to true, it will create a worker group that will be shared. However,
> this worker group will never be closed causing the JVM shutdown hook to never
> be triggered. The benchmark was able to work normally if the share
> configuration is disabled.
> Need to find a way to shutdown the worker group gracefully without losing the
> shared worker group benefit.
