Salesforce Bulk API behavior with Talend

When using Talend to move records from Oracle DB to SFDC i got an error like this.

Exception in component tSalesforceOutputBulkExec_1_tSBE
[AsyncApiException  exceptionCode='InvalidBatch'
exceptionMessage='Records not processed'
]

after researching and trying lot options I found Talend taken default schema when I refreshed schema and it worked fine.
