Suresh Srinivas commented on HDFS-5104:
---------------------------------------
Comments:
# Comment {{".." is only allowed in /.reserved/.inodes/... path}}, since you
are talking .. indicating remaining with path with trailing ... could be
confusing. How about {{".." is allowed in path starting with
/.reserved/.inodes}}
# Hardcoded ".reserved" should use FSDirectory.DOT_RESERVED_STRING
# Hardcoded ".inodes" should use FSDirectory.DOT_INODES_STRING
# Please do cluster shutdown in try finally block in tests
# Please format the code correctly - while building testPath there is no space
before and after +
# How do you propose to handle if some passes
{{/.reserved/.inodes/<root_inode>/..}}. It should be an error condition right,
instead of just returning the root?

> 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/.."
