Subject [jira] Commented: (HADOOP-4044) Create symbolic links in HDFS
Date Tue, 07 Oct 2008 22:12:44 GMT

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

> So is replacing 'return false;' with 'return new FSLinkBoolean(false)'. 

That's not a fair comparison.  I was talking about shorter names versus longer names.  You
are talking about throwing exceptions versus adding a bit of code to return a value.  Both
involve more-or-less code, but in one case that's the only issue, in the other there's a lot
more to it.

> 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.
