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

    [ https://issues.apache.org/jira/browse/HDFS-245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12755099#action_12755099 ] 

Eli Collins commented on HDFS-245:
----------------------------------

Discussed with Dhruba. I'll start putting together a design doc to cover the above questions/comments which deserve some more discussion. Will also start on a test plan and user guide. 

I rebased the latest diffs against trunk and have patches for hdfs, common and mapreduce. I'll file jiras for the last two and update each with the relevant patch.

> 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.
