Elek, Marton created HDDS-378:
---------------------------------
Summary: 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
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)
