[jira] [Created] (HDFS-7416) Revisit the abstraction between NameNodeRpcServer, FSNameSystem and FSDirectory

Haohui Mai created HDFS-7416:
--------------------------------

             Summary: Revisit the abstraction between NameNodeRpcServer, FSNameSystem and FSDirectory
                 Key: HDFS-7416
                 URL: https://issues.apache.org/jira/browse/HDFS-7416
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai


{{NameNodeRpcServer}}, {{FSNameSystem}} and {{FSDirectory}} implement the namespace of the NN. In the current implementation the boundary of these classes are not fully clear.

This jira tracks the efforts of clarifying the boundaries between these three classes so that they can be more easily maintained in the long term.
