## After stopping the impdp job interactively, then looking at
## DBA_DATAPUMP_JOBS, you'll have the job name, for example
## sys_import_full_01.  To attach to the stopped job:
                                                                                
impdp datapump/datapump attach=sys_import_full_01
                                                                                
## Then, at the Import> prompt, enter:
## Import> kill_job
