> Allow users to map source columns to Java and Avro types based on rules rather than a list.
> About half the data types on my current project are NUMERIC, and many of those have a SCALE of 0. It would be helpful to be able to process those as Integers or Longs. The map-column-java feature is helpful, but it requires continuous surveillance of the source tables and maintenance of lists of columns and what type they should be mapped to.
> It would be helpful to be able to create a rules-based interpretation of the type inference provided by Sqoop.
