Neil Joshi commented on HDDS-5813:
----------------------------------

see [https://github.com/apache/ozone/pull/2945] for patch that allows selecting 
OmTransport through configuration between the s3gateway and the ozone manager.  
Selects between hadoop rpc (HDDS-5581) and Grpc (HDDS-4440) OmTransport using 
"ozone.om.transport.class" configuration - 
org.apache.hadoop.ozone.om.protocolPB.Hadoop3OmTransportFactory (default) or 
org.apache.hadoop.ozone.om.protocolPB.GrpcOmTransportFactory.

> Support hadoop rpc ozone client (non persistent connection)

> Look into S3g gRPC feature to support non-persistent connection with original 
> hadoop rpc based ozone client.
> Preliminary, this requires:
> i.) configurable service provider META-INF for OmTransportFactory.  Selecting 
> between GprcOmTransport and Hadoop3OmTransport.
> ii.) interface for OzoneClientProducer; through configuration selecting 
> between Grpc based OzoneClientProducer (persistent connection) and original 
> hadoop rpc (new connection per request).
