---------------------------------
Assignee: Elek, Marton
> Remove dependencies between hdds/ozone and hdfs proto files
> -----------------------------------------------------------
>
> Key: HDDS-378
> URL: https://issues.apache.org/jira/browse/HDDS-378
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Elek, Marton
> Assignee: Elek, Marton
> Priority: Major
> Labels: newbie
>
> It would be great to make the hdds/ozone proto files independent from hdfs
> proto files. It would help as to start ozone with multiple version of hadoop
> version.
> Also helps to make artifacts from the hdds protos: HDDS-220
> Currently we have a few unused "hdfs.proto" import in the proto files and we
> use the StorageTypeProto from hdfs:
> {code}
> cd hadoop-hdds
> grep -r "hdfs" --include="*.proto"
> common/src/main/proto/ScmBlockLocationProtocol.proto:import "hdfs.proto";
> common/src/main/proto/StorageContainerLocationProtocol.proto:import
> "hdfs.proto";
> cd ../hadoop-ozone
> grep -r "hdfs" --include="*.proto"
> common/src/main/proto/OzoneManagerProtocol.proto:import "hdfs.proto";
> common/src/main/proto/OzoneManagerProtocol.proto: required
> hadoop.hdfs.StorageTypeProto storageType = 5 [default = DISK];
> common/src/main/proto/OzoneManagerProtocol.proto: optional
> hadoop.hdfs.StorageTypeProto storageType = 6;
> {code}
> I propose to
> 1.) remove the hdfs import statements from the proto files
> 2.) Copy the StorageTypeProto and create a Hdds version from it (without
> PROVIDED)
