Xiaoyu Yao commented on HDDS-1525:
----------------------------------
One issue I found is that RPCClient should not implement KeyProviderTokenIssuer
(Hadoop3 only) because it is shared between BasicOzoneFileSystem and
OzoneFileSystem. In the case of BasicOzoneFileSystem for Hadoop 2, this
interface won't be available.
{code}
public class RpcClient implements ClientProtocol, KeyProviderTokenIssuer {
{code}
> Mapreduce failure when using Hadoop 2.7.5

> Integrate Ozone(0.4 branch) with Hadoop 2.7.5, "hdfs dfs -ls /" can pass,
