---------------------------------------------

             Summary: Explicitly mark NOT NULL columns
                 Key: SQOOP-3388
                 URL: https://issues.apache.org/jira/browse/SQOOP-3388
             Project: Sqoop
          Issue Type: Wish
          Components: metastore
    Affects Versions: 1.4.7
            Reporter: Tomas Sebastian Hätälä
             Fix For: 1.5.0


It would be great to pass as much meta-information attributes as possible 
between systems. At least avro file format offers the possibility to maintain 
information regarding e. g. PK columns, NOT NULL constraints, etc.
