    Description

      In HBASE-25976, we introduced a master based replication tracker to not depend on zk, but the problem is that we will always fetch the whole region server list, from every region server, which will become a performance issue when the cluster has lots of region servers.

      So we need to introduce a new API to sync the live region server list. As the region server list will not be changed too much, we should have a way to detect this and not pass the full list.
