Subject [jira] [Created] (HDFS-4325) ClientProtocol.createSymlink parameter dirPerm invalid
Date Wed, 19 Dec 2012 08:11:13 GMT
Binglin Chang created HDFS-4325:

             Summary: ClientProtocol.createSymlink parameter dirPerm invalid
                 Key: HDFS-4325
                 URL: https://issues.apache.org/jira/browse/HDFS-4325
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Binglin Chang

   * @param link The path of the link being created.
   * @param dirPerm permissions to use when creating parent directories
   * @param createParent - if true then missing parent dirs are created
   *                       if false then parent must exist
According to javadoc, auto created parent dir's permissions will be dirPerm, but in fact directory
permissions are always inherit from parent directory plus u+wx.
IMHO, createSymlink behavior should be the same as create, which also inherit parent dir permission,
so the current behavior makes sense, but the related dirPerm parameters should be removed
cause it is invalid and confusing.
