  || Switching to Hadoop's local mode || Local Mode || Low || None || Main 
change is 10-20x performance slowdown. Also, local mode now uses the same UDF 
interfaces to execute UDFs as the MR mode. ||
  || Removing support for Load-Stream or Stream-Store optimization || Streaming 
|| Low to None || None || This feature was never documented so it is unlikely 
it was ever used ||
  || We no longer support serialization and decerialization via load/store 
functions || Streaming || Unknown but hopefully low to medium || Implement new 
PigToStream and StreamToPig interfaces for non-standard serialization || 
LoadStoreRedesignProposal ||
+ || Output part files now have a "-m-" and "-r" in the name || Output file 
names || Low to medium || If you have a system which depends on output file 
names tghe names now have changed from part-XXXXX to part-m-XXXXX if the output 
is being written from the map phase of the job or part-r-XXXX if it is being 
written from the reduce phase || || 
  || Removing BinaryStorage builtin || Streaming || Low to None || None || As 
far as we know, this class was only used internally by streaming ||
  || Removing Split by file feature || Split by File || Low to None || Input 
format of the loader would need to support this || We don't know that this 
feature was widely/ever used ||
  || Local files no longer accessible from cluster || Access to Local Files 
from Map-Reduce Mode || low to none || copy the file to the cluster using 
copyToLocal command prior to the load || This feature was not documented ||
