Review comment:
Yes, meaning of that line is not clear. Thanks. The change in code
does NOT support hadoop RPC for the s3 gateway based on the cached client
(single) and the OmTransport (service provider for factory selecting
GrpcOmTransport).
> In that case, for the client, it can be swapped with a prior release
hadoop rpc support
To be clear, I meant that we could use a prior version (pre Grpc s3g) of the
gateway that supported hadoop rpc. Use the prior s3gateway version in the
cluster.
The server supports both s3 gateways, hadoop rpc and Grpc.
