-------------------------------------
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.
