Subject [jira] Commented: (HADOOP-4044) Create symbolic links in HDFS
Date Thu, 09 Oct 2008 22:50:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638421#action_12638421

Tsz Wo (Nicholas), SZE commented on HADOOP-4044:

Doug> Links are clearly not programming errors or client code errors.

It depends on how the API is defined.  e.g. we could define the API open(Path f) such that
the parameter f is supposed to be a non-linked path.  An exception will be thrown if the client
codes use it with a linked path.

> 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.
