  Second, '''you can no longer use load/store functions for 
(de)serialization.''' A new interface has been defined that needed to be 
implemented for custom (de)serializations. The default (PigStorage) format will 
continue to work. This formar is now implemented by a class called 
org.apache.pig.impl.streaming.PigStreaming that can be also used directly in 
the streaming statement. Details of the new interface are describe in 
http://wiki.apache.org/pig/LoadStoreRedesignProposal.
  
- We have also removed org.apache.pig.builtin.BinaryStorage loader/store 
function and org.apache.pig.builtin.PigDump which were only used from within 
straming. They can be restored if needed - we would just need to implement the 
corresponding Input/OutputFormats.

  In Pig 0.7.0, you can no longer do this and if this functionality is still 
desired, you can add the copy into your script manually:
  
  {{{
- fs copyFromLocal src dist
+ fs -copyFromLocal src dist
  A = load 'dist';
  ....
  }}}
