Date Fri, 09 Oct 2015 18:57:05 GMT
John Todd created SQOOP-2612:
--------------------------------

             Summary: Allow rules-based column mapping
                 Key: SQOOP-2612
                 URL: https://issues.apache.org/jira/browse/SQOOP-2612
             Project: Sqoop
          Issue Type: New Feature
          Components: codegen, connectors, test, tools
    Affects Versions: 1.4.6
            Reporter: John Todd
            Priority: Minor


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.
