["Eli Collins (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HDFS-245?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eli Collins updated HDFS-245:
-----------------------------

    Attachment: symlink21-hdfs.patch
                symlink21-common.patch

Here are patches that merge in the latest changes on trunk and move the symlink implementation off FileSystem and onto AbstractFileSystem, decided not to have a duplicate implementation for FileSystem since clients are moving off it, reasonable?

> HDFS should support symbolic links. A symbolic link is a special type of file that contains a reference to another file or directory in the form of an absolute or relative path and that affects pathname resolution. Programs which read or write to files named by a symbolic link will behave as if operating directly on the target file. However, archiving utilities can handle symbolic links specially and manipulate them directly.
