Load and Index Candidates error

Content (required):

Dear Colleagues,

I am implementing the recruiting module for a client but I'm not able to see candidates in candidate search (results is always 0).

The process Load and Index Candidates went wrong Error is "The mapping for an index does not exists, exiting from the indexing job, Please check the logs"

Here are the parameters entered

Would anyone be able to tell me if any other parameters need to be entered?
