When i submit a job through the web service interface of condor using the SOAP API, the job can;t be scheduled at once.So I remove the job from the condor_pool using the command "condor_rm" from the command line.But,when i use the command "condor_q" to observe whether this job has bean removed,i found it's status is changed to 'X'.So,i want to know how to remove the job so that when i use the command "condor_q", it will really be removed .
