[jira] Created: (HDFS-932) Resolve NN symlinks internally

Resolve NN symlinks internally
------------------------------

                 Key: HDFS-932
                 URL: https://issues.apache.org/jira/browse/HDFS-932
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
            Reporter: Eli Collins
            Assignee: Eli Collins


In the current symbolic link code an exception is thrown from the NameNode to FileContext for every symbolic link in a path. As an optimization to remove these round trips the NameNode can resolve symbolic links that have relative or absolute targets internally without going up to FileContext. Partially and fully qualified link targets still need to get resolved by FileContext since they may refer to different file systems.
