> This jira tracks the effort of moving the following two parts to {{hadoop-hdfs-client}}
module:
> * {{*Peer.java}} classes
> * static helper methods in {{TcpPeerServer}}
> In {{org.apache.hadoop.hdfs.net}} package, the {{Peer}} classes should be moved to {{hadoop-hdfs-client}}
module as they are used in client, while {{PeerServer}} classes stay in {{hadoop-hdfs}} module.
For the static helper methods in {{TcpPeerServer}}, we need to move them out of the {{TcpPeerServer}}
class and put them in client module. 
> Meanwhile, we need to move the related classes in {{org.apache.hadoop.hdfs.protocol.datatransfer.sasl}}
packages as they're used by client module. Config keys should also be moved.
> The checkstyle warnings can be addressed in [HDFS-8979 | https://issues.apache.org/jira/browse/HDFS-8979],
and removing the _slf4j_ logger guards when calling {{LOG.debug()}} and {{LOG.trace()}} can
be addressed in [HDFS-8971 | https://issues.apache.org/jira/browse/HDFS-8971].
