> Key: SQOOP-1606
> URL: https://issues.apache.org/jira/browse/SQOOP-1606
> Project: Sqoop
> Issue Type: Bug
> Reporter: Gwen Shapira
> Assignee: Gwen Shapira
>
> Pretty rare, but can happen (that is - did happen...):
> Assume a table, TABLE1 with an index, also named TABLE1.
> The segments for TABLE1 table and TABLE1 index are in two different
> tablespaces, and both have identical relative_fno.
> In that case, the input splits generated by getOracleDataChunksExtent will
> include block ranges that belong to the index and can overlap with some of
> the "correct" block ranges. This can lead to duplicate data when importing.
> The solution should be to use object_type when filtering to limit ourselves
> to tables and partitions.
