             Summary: Federation Mount Table State Store internal API
                 Key: HDFS-10880
                 URL: https://issues.apache.org/jira/browse/HDFS-10880
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: fs
            Reporter: Jason Kace
            Assignee: Jason Kace


The Federation Mount Table State encapsulates the mapping of file paths in the global namespace
to a specific NN(nameservice) and local NN path.  The mount table is shared by all router
instances and represents a unified view of the global namespace.   The state store API for
the mount table allows the related records to be queried, updated and deleted.
