Subject [jira] [Created] (HDFS-9304) Add HdfsClientConfigKeys class to TestHdfsConfigFields#configurationClasses

-----------------------------------

             Summary: Add HdfsClientConfigKeys class to TestHdfsConfigFields#configurationClasses
                 Key: HDFS-9304
                 URL: https://issues.apache.org/jira/browse/HDFS-9304
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Mingliang Liu
            Assignee: Mingliang Liu


*tl;dr* Since {{HdfsClientConfigKeys}} holds client side config keys, we need to add this
class to {{TestHdfsConfigFields#configurationClasses}}.

Now the {{TestHdfsConfigFields}} unit test passes because {{DFSConfigKeys}} still contains
all the client side config keys, though marked @deprecated. As we add new client config keys
(e.g. [HDFS-9259]), the unit test will fail with the following error:
{quote}
hdfs-default.xml has 1 properties missing in  class org.apache.hadoop.hdfs.DFSConfigKeys
{quote}

If the logic is to make the {{DFSConfigKeys}} and {{HdfsClientConfigKeys}} together cover
all config keys in {{hdfs-default.xml}}, we need to put both of them in {{TestHdfsConfigFields#configurationClasses}}.
