Subject [jira] Commented: (HADOOP-4044) Create symbolic links in HDFS
Date Fri, 03 Oct 2008 23:33:44 GMT

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

> I actually don't think returning some base class unrelated to member/api is clean. [
... ]

Except it is related.  The contract of all of these methods has changed, so that they can
either return, e.g., an open file or a link.  We need a uniform way to represent this.   A
two-step API is unacceptable for performance reasons.  A base return class thus seems like
a fine way to do this.  What would you suggest instead?

> 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.
