Unable to schedule exam for Spark developer. As per suggestion given in one of the previously replied answer, i tried to register my self MapR Certified Spark Developer 1.6 (MCSD) . When i provide my code(which i got in my official training) it says code is not valid. can you please help me here.
To be more clear on code validity, i have schedule this exam for 4th Jan but cancelled on 2 jan. so my voucher is valid but with new configured exam its not working.
