[jira] [Created] (SQOOP-3370) Investigate sqoop import + --incremental + lastmodified + --as-sequencefile use case

Boglarka Egyed created SQOOP-3370:
-------------------------------------

             Summary: Investigate sqoop import + --incremental + lastmodified + --as-sequencefile use case
                 Key: SQOOP-3370
                 URL: https://issues.apache.org/jira/browse/SQOOP-3370
             Project: Sqoop
          Issue Type: Improvement
    Affects Versions: 1.4.7
            Reporter: Boglarka Egyed


I checked both the [User Guide|https://sqoop.apache.org/docs/1.4.7/SqoopUserGuide.html#_incremental_imports] and the Apache Sqoop Cookbook and it seems that there is no documentation regarding the supported file formats in case of the sqoop import + --incremental + lastmodified use case.

There is no guideline for sqoop import + --incremental + lastmodified + --as-sequencefile either. I also checked the code and couldn't find any test to cover this nor any guideline how to do incremental merge import properly with Sequence file however it should be checked, tested and well documented.
