-----------------------------------
Summary: Oraoop import can end up with overlapping input splits,
generating duplicate data
Key: SQOOP-1606
URL: https://issues.apache.org/jira/browse/SQOOP-1606
Project: Sqoop
Issue Type: Bug
Reporter: 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.
