-----------------------------------
Summary: Sqoop2: Extracting sequence files may result in duplicates
Key: SQOOP-2811
URL: https://issues.apache.org/jira/browse/SQOOP-2811
Project: Sqoop
Issue Type: Bug
Affects Versions: 1.99.6
Reporter: Abraham Fine
Assignee: Abraham Fine
In the hdfs extractor we use:
```
if (start > filereader.getPosition()) {
filereader.sync(start); // sync to start
}
```
to jump to the correct point in the sequence file that we want to extract.
If the sequence file is small, multiple start points may `sync` to the same
point and we could end up extracting the same record multiple times.
