Arpit Agarwal commented on HDFS-10391:
--------------------------------------
Hi [~xyao],
I tried making these two changes and hit a bunch of unit test failures.
bq. Line 433-463 (original NamenodeRPCServer.java): should we remove the
service related RPCs from the client RPC server as we are not allow fallback
bq. Line 343-345: should we ensure only the service RPCs are added/set here?
I think the broken tests need to be updated. Is it okay if we address these
two remaining ideas in a follow up Jira?

> The NameNode should always be setup with a service RPC port so that it does
> not have to be explicitly enabled by an administrator.
