> We need to decide how want to make this new classloader functionality available to users.
  
> One use case is making per-table class loaders availiable.   This would allow the user
to set a per table property like the following.
> {noformat}
>    table.classpath=hdfs://nn:8092/myApp
> {noformat}
> Setting this would allow iterators specific to the table to be loaded from a given location.
  Currently when a user iterator is placed in lib/ext all tables see the iterator.
> Another possible use case is per-scan classpath.
