Zheng Hu commented on HBASE-20578:
----------------------------------
bq. To break cyclic dependency, can subclass of
HBaseInterClusterReplicationEndpoint be created in hbase-rsgroup module to
accommodate the method (fetchSlavesAddresses) where rs group information is
needed ?
Move the HBaseInterClusterReplicationEndpoint creation to hbase-rsgroup can
not solve the cyclic dependency ? the hbase-server module will still need to
depend on the hbase-rsgroup module. IMO, can just create a new subclass named
HBaseRSGroupReplicationEndpoint. If want to enable rsgroup replication
feature, just load the class in hbase-server module dynamically... just like
the RSGroupAdminEndpoint class, it's used by hbase-server but not explicitly
written in the code.
Thanks.

> When source tables belong to non-default region server group(s) and there are
> region server group counterpart in the target cluster, we should support
