Subject [jira] [Commented] (HADOOP-9043) winutils can create unusable symlinks
Date Wed, 17 Apr 2013 18:01:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13634257#comment-13634257
] 

Ivan Mitic commented on HADOOP-9043:
------------------------------------

Thanks Chris for addressing the comments.

bq. Could you elaborate on this? There are 2 call sites for this method, and they both need
to convert the result to string, which is why I kept the method returning string.
I just meant to have the method explicitly return a File instead of a String. This way you
can remove the Windows specific comment in code and everything implicitly works.

> In general, the winutils symlink command rejects attempts to create symlinks targeting
a destination file that does not exist.  However, if given a symlink destination with forward
slashes pointing at a file that does exist, then it creates the symlink with the forward slashes,
and then attempts to open the file through the symlink will fail.
