Subject [jira] [Created] (HADOOP-8015) ChRootFileSystem should extend FilterFileSystem
Date Thu, 02 Feb 2012 18:58:57 GMT
ChRootFileSystem should extend FilterFileSystem
-----------------------------------------------

                 Key: HADOOP-8015
                 URL: https://issues.apache.org/jira/browse/HADOOP-8015
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
    Affects Versions: 0.23.0, 0.24.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


{{ChRootFileSystem}} simply extends {{FileSystem}}, and attempts to delegate some methods
to the underlying mount point.  It is essentially the same as {{FilterFileSystem}} but it
mangles the paths to include the chroot path.  Unfortunately {{ChRootFileSystem}} is not delegating
some methods that should be delegated.  Changing the inheritance will prevent a copy-n-paste
of code for HADOOP-8013 and HADOOP-8014 into both {{ChRootFileSystem}} and {{FilterFileSystem}}.
