Duo Zhang updated HBASE-25649:
------------------------------
Release Note:
Introduced a ClusterInfoProvider as a bridge for LoadBalancer implementation to
get cluster information and operate on the cluster, so the LoadBalancer
implementation does not need to depend on HMaster/MasterServices directly. So
then we could move most LoadBalancer related code to hbase-balancer module.
MasterClusterInfoProvider is the actual implementation class for
ClusterInfoProvider.
Moved most unit tests for load balancer to hbase-balancer module, unless it
requires starting a mini cluster.
RSGroupBasedLoadBalancer and related code are still in hbase-server module. As
we still have lots of migration and compatibility code, which makes it deeply
tied togather with HMaster/MasterServices. We could try to move it again in
4.0.0, when we have purged the migration and compatibility code.
> Complete the work on moving all the balancer related classes to
> hbase-balancer module
