Duo Zhang commented on HBASE-26231:
-----------------------------------
No, we still have the ability to dynamically update the configurations for
master. Sorry for my bad English.
This issue aims to provide the updateConfiguration ability without implementing
the AdminService. But later, I found that in our current rpc code base, we just
get an AdminService with the master address and then make rpc call to master,
which means if we make MasterRpcServices not implement AdminService, the old
client will be broken.
So the final solution is to still make MasterRpcServices implement
AdminService, but only throw DoNotRetryIOException for the methods we can not
support on master. You can see the PR for HBASE-25288.
Thanks for taking a look. [~bbeaudreault]
