Uma Maheswara Rao G updated HDDS-6209:
--------------------------------------
Description:
In EC branch code, we removed the client side default configurations and moved
the default configurations to server side.
In case of client upgraded with newer client, but server are still old, will
not understand the situation of client config unavailability as older server
always expects the replication configs from client.
I think as part of S3G, there are some implementations to handle the version
incompatibilities. example OM handshaking it's version to client and client
maintaining it's current version could help to solve the issue.
