My HDPCD Exam was scheduled on 19th feb 2018 . Cluster was not up and running , connection was not present with name node . After struggling 2 hours proctor said he will be marking attempt as system issue . I raised this issue with exams local and certification support for credit /refund of exam fee. Could you pls look into it and try to expedite the process ? Candidate id 2685885360 . Exams local team said that it is lending with Horton works .
