Question

I am transferring files from a directory on a remote host and a trigger fires jobs when interval arrives for this job.But i want be sure that if a job still working on a storage (downloading of files not yet finished) when trigger fire time arrives ,quartz going to skip this interval.I try to use this
c r on_trigger.MISFIRE_INSTRUCTION_DO_NOTHING but i seems it only for if there is no available thread for job.

public CronTrigger scheduleJob(RemoteJob job, String cronExpression,Date firstFireTime) throws SchedulerException, ParseException {
    JobDetail jobDetail = new JobDetail(job.getDescription(), job.getName(), job.getClass());
    CronTrigger crTrigger = new CronTrigger(
            "cronTrigger", job.getName(), cronExpression);       
    scheduler.scheduleJob(jobDetail, crTrigger);    
    crTrigger.setStartTime(firstFireTime);
    crTrigger.setMisfireInstruction(CronTrigger.MISFIRE_INSTRUCTION_DO_NOTHING);
    return crTrigger;

}

Create a TriggerListener that tracks if one of your download jobs is running, and and then return true for vetoing the execution of the other type of job.
