Usage

revoscalepy.rx_cleanup_jobs(job_info_list: typing.Union[revoscalepy.computecontext.RxRemoteJob.RxRemoteJob,
    list], force: bool = False, verbose: bool = True)

Description

Removes the artifacts for the specified jobs.

If job_info_list is a RxRemoteJob object, rx_cleanup_jobs attempts to remove the artifacts. However, if the job has successfully completed and force is False, rx_cleanup_jobs issues a warning saying to either set force=True or use rx_get_job_results to get the results and delete the artifacts.

If job_info_list is a list of jobs, rx_cleanup_jobs attempts to apply the cleanup rules for a single job to each element in the list.

Arguments

job_info_list

The jobs for which to remove the artifacts, this can be a list of jobs or a single job

force

True indicates the cleanup should happen regardless of whether or not the job status can be determined and job results have already been retrieved. False indicates that the should be cleaned up by calling rx_get_job_results or the job should have completed unsuccessfully (such as by using rx_cancel_job).

verbose

If True, will print the directories/records being deleted.

Returns

This function does not return a value
