> Currently the {{org.apache.hadoop.hdfs.NameNodeProxies}} class is used by 
> both {{org.apache.hadoop.hdfs.server}} package (for server side protocols) 
> and {{DFSClient}} class (for {{ClientProtocol}}). The {{DFSClient}} class 
> should be moved to {{hadoop-hdfs-client}} module (see [HDFS-8053 | 
> https://issues.apache.org/jira/browse/HDFS-8053]). As the 
> {{org.apache.hadoop.hdfs.NameNodeProxies}} class also depends on server side 
> protocols (e.g. {{JournalProtocol}} and {{NamenodeProtocol}}), we can't 
> simply move this class to the {{hadoo-hdfs-client}} module as well.
> This jira tracks the effort of moving {{ClientProtocol}} related static 
> methods in {{org.apache.hadoop.hdfs.NameNodeProxies}} class to 
> {{hadoo-hdfs-client}} module. A good place to put these static methods is a 
> new class named {{NameNodeProxiesClient}}.
> The checkstyle warnings can be addressed in [HDFS-8979], and removing the 
> _slf4j_ logger guards when calling {{LOG.debug()}} and {{LOG.trace()}} can be 
> addressed in [HDFS-8971].
