RunUntilCanceled when job is queued cannot be set via API, can be set via GUI RRS feed

    In HPC Pack 2012 R2 if I submit a job with RunUntilCanceled = true then at some point do:

    job.RunUntilCanceled = false;
    job.Commit();

    then I get 

    "Microsoft.Hpc.Scheduler.Properties.SchedulerException: The property RunUntilCanceled cannot be set when the job is in state Queued."

    But via the HPC Cluster Manager GUI I can go to Job Management and select a queued job -> right click -> Modify job -> uncheck "Run job until cancelled or runtime expires" -> "Modify" and it modifies the job as expected.

    How can I do this via the .Net API?

    It works as expected via the CLI, so to call from C# you can do something like this:

    Process.Start(new ProcessStartInfo("job", string.Format("modify {0} /rununtilcanceled:false /scheduler:{1}", job.Id, hpcHeadnode)){CreateNoWindow = true, UseShellExecute = false}).WaitForExit();

    We haven't exposed the jobModify interface in the scheduler API. At this time, you can do below as we do in GUI and CLI:

    Please add reference to Microsoft.Hpc.Scheduler.Store and with below methods:

        Microsoft.Hpc.Scheduler.Store.SchedulerStoreHelpers.JobModify(ISchedulerStore store, int jobId, params StoreProperty[] changedProps)

    I get the same exception when calling this method.

    I call this:

    SchedulerStoreHelpers.JobModify(SchedulerStore.Connect("MyHeadNode"), job.Id, new StoreProperty("RunUntilCanceled", false));

    Here is the stacktrace

    Microsoft.Hpc.Scheduler.Properties.SchedulerException : The property RunUntilCanceled cannot be set when the job is in state Queued.

    However I can still go in to the GUI and uncheck "Run until job is canceled" on the job and it works as expected.

    Also I can call on the command line:

    job modify [jobid] /rununtilcanceled:false
    and it works as expected.
