Subject [jira] Commented: (HADOOP-4044) Create symbolic links in HDFS
Date Thu, 09 Oct 2008 23:30:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638436#action_12638436

Doug Cutting commented on HADOOP-4044:
--------------------------------------

> we could define the API open(Path f) such that the parameter f is supposed to be a non-linked
path.

Does calling something an "error" really make it an "error"?  It seems like the only motivation
to call this an error is to justify using exceptions to handle links, not that it would in
fact be a user or program error to call it in this way.  Rather, it would be an expected,
documented, supported event, but we'd call it an error anyway, because otherwise we'd have
to actually model the functionality in our API.

> 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.
