Subject [jira] [Created] (SQOOP-360) Duplication of the record in the case of using import mode
Date Wed, 12 Oct 2011 09:03:11 GMT
Duplication of the record in the case of using import mode 

                 Key: SQOOP-360
                 URL: https://issues.apache.org/jira/browse/SQOOP-360
             Project: Sqoop
          Issue Type: Bug
          Components: connectors
    Affects Versions: 1.3.0
            Reporter: SATOSHI KONDO

When I use Import mode of Sqoop,
I get duplicate records.

This occurs on condition of the following. 

1.Use Import mode of Sqoop
2.Set a character type to "split-by" parameter 
3.Set a big value to "num-mappers" parameter

The big value is a relatively large thing as compared with the total number of records. 
For example, 
when total number of records is 10,
I set 100 to "num-mappers" parameter.

I expect to get 10 records.
But I get 10 or more lines.
