> Key: SQOOP-1154
> URL: https://issues.apache.org/jira/browse/SQOOP-1154
> Project: Sqoop
> Issue Type: Bug
> Affects Versions: 1.99.2
> Reporter: Jarek Jarcec Cecho
> Fix For: 1.99.3

> Attachments: bugSQOOP-1154.patch, import_test_case.patch

> Attached is test case that will use Varchar partitioner to generate 3, 5, 10
> and 13 partitions for interval "Breezy Badger" to "Warty Warthog". For all
> cases generated partitions looks like the following:
> {code}
> 'Bree' <= VCCOL AND VCCOL < SOME_VALUE
> SOME_VALUE <= VCCOL AND VCCOL <= 'Wart'
> {code}
> As {{'Warty Warthog' > 'Wart'}}, the last value will be never imported. Also
> similarly as {{'Bree' < 'Breezy Badger'}}, additional values might be
> imported as well (for example 'Breedy Budget'). I think that the varchar
> partitioner must have the interval boundaries there without any truncation,
> for example:
> {code}
> 'Breezy Badget' <= VCCOL AND VCCOL < SOME_VALUE
> SOME_VALUE <= VCCOL AND VCCOL <= 'Warty Warthog'
> {code}
