even if you interrupt data bump job on shell therefore you have to do the following :-
as / as sysdba run the below query :
select * from dba_datapump_jobs
After checking the status of each one,
run the following :-
DECLARE
h1 NUMBER;
BEGIN
h1:=DBMS_DATAPUMP.ATTACH(‘JOB_NAME’,’OWNER_NAME’);
DBMS_DATAPUMP.STOP_JOB (h1,1,0);
END;
/
