I have mapped the columns correctly to match with the API's column names. What will be the issue.?
Thank u so much for any replies!!

Whenever Salesforce throws "Invalid Batch" , it means that there is an issue with one of the columns in header. You can go into Salesforce bulk monitor and go to the particular job. It will give the exact name of the column which is causing problems. Generally there can be following reasons : 

1) Typo in field API name

2) You don't have access to edit that particular API 

3) Number of header and fields not matching.
