Registering Jars from HDFS?

[Zach Bailey]

                        Is it possible to feed a path of the format 
"hdfs:///path/to/my.jar" to the REGISTER command in Pig? I was recently 
watching some of the tutorials on Amazon's Elastic MapReduce and their version 
of Pig appears to support this ... was wondering if this is also available in 
the "vanilla" distribution as well, and if not, how hard is it to patch in? Or 
is this planned for a future version? I'm currently using 0.7 ...
                        
                
        Thanks!Zach
