UDI-28002 means that data pump found an underlying error ORA-28002 when authenticating the login user. The code is actually a warning rather than an error. It can be ignore or you may look for a solution to ORA-28002.
Such error doesn't return control to OS, your operation is not interrupted and still running, just be patient.
