How do I kill Oracle DataPump expdp job stuck in DEFINING state? My job failed because dump file already existed.
Now it's stuck in DEFINING state.

How do I stop/kill it?

declare
h1 number;
BEGIN
h1 := DBMS_DATAPUMP.ATTACH('EXPORT_TABLE_2017_1205_1402',user);
--DBMS_DATAPUMP.STOP_JOB (h1,1,0);
DBMS_DATAPUMP.stop_job (h1, 1);
DBMS_DATAPUMP.detach (h1);
END;
/

DROP TABLE SYS.EXPORT_TABLE_2017_1205_1402;
