Subject [jira] [Created] (HDFS-5104) Support dotdot name in NFS LOOKUP operation
Date Thu, 15 Aug 2013 23:46:49 GMT
Brandon Li created HDFS-5104:
--------------------------------

             Summary: Support dotdot name in NFS LOOKUP operation
                 Key: HDFS-5104
                 URL: https://issues.apache.org/jira/browse/HDFS-5104
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: nfs
    Affects Versions: 3.0.0
            Reporter: Brandon Li
            Assignee: Brandon Li


Procedure LOOKUP searches a directory for a specific name and returns the file handle for
the corresponding file system object. NFS client sets filename as ".." to get the parent directory
information.

Currently ".." is considered invalid name component. We only allow ".." when the path is an
inodeID path as "/.reserved/.inodes/.."
