             Summary: Provide an option automatically choose one mapper when neither primary key is defined nor split by column is provided
                 Key: SQOOP-2191
                 URL: https://issues.apache.org/jira/browse/SQOOP-2191
             Project: Sqoop
          Issue Type: Bug
            Reporter: Venkat Ranganathan
            Assignee: Venkat Ranganathan


This is typically an issue when import-all-tables is used on a schema.   There may be tables without any primary key and currently the only option is identify them and exclude them proactively. 

The solution proposed is to add an option to automatically reset the num mappers to one so that import-all-tables can continue by importing such tables with one mapper
