Quartz.NET scheduler.Interrupt(jobKey) is interrupting all active jobs

问题

Should the method only interrupt the job as defined by the jobKey? I've ran some tests and it seems to interrupt all of the active jobs currently running.

I am using a restful web api to connect to the remote scheduler to create/interrupt/delete jobs.

Api service code:

public void DeleteJob(JobKey jobKey)
{
    var scheduler = _clientQuartzScheduler.GetScheduler();

    var executingJobs = scheduler.GetCurrentlyExecutingJobs();

    if (executingJobs.Any(x => x.JobDetail.Key.Equals(jobKey)))
    {
        scheduler.Interrupt(jobKey);
    }

    scheduler.DeleteJob(jobKey);
}

Quartz remote scheduler app settings are:

<add key="quartz.threadPool.type" value="Quartz.Simpl.SimpleThreadPool, Quartz" />
<add key="quartz.threadPool.threadCount" value="10" />
<add key="quartz.threadPool.threadPriority" value="Normal" />

<add key="quartz.scheduler.exporter.type" value="Quartz.Simpl.RemotingSchedulerExporter, Quartz" />
<add key="quartz.scheduler.exporter.port" value="555" />
<add key="quartz.scheduler.exporter.bindName" value="QuartzScheduler" />
<add key="quartz.scheduler.exporter.channelType" value="tcp" />
<add key="quartz.scheduler.exporter.channelName" value="httpQuartz" />
<add key="quartz.scheduler.exporter.rejectRemoteRequests" value="false" />

<add key="quartz.jobStore.clustered" value="false" />
<add key="quartz.jobStore.misfireThreshold" value="60000" />
<add key="quartz.jobStore.type" value="Quartz.Impl.AdoJobStore.JobStoreTX, Quartz" />
<add key="quartz.jobStore.lockHandler.type" value="Quartz.Impl.AdoJobStore.UpdateLockRowSemaphore, Quartz" />
<add key="quartz.jobStore.useProperties" value="true" />
<add key="quartz.jobStore.dataSource" value="default" />
<add key="quartz.jobStore.tablePrefix" value="QRTZ_" />
<add key="quartz.jobStore.driverDelegateType" value="Quartz.Impl.AdoJobStore.MySQLDelegate, Quartz" />   

<add key="quartz.dataSource.default.provider" value="MySql-65" />
<add key="quartz.dataSource.default.connectionStringName" value="DatabaseConnectionString" />

The api client settings are:

properties["quartz.scheduler.instanceName"] = "RemoteClient";
properties["quartz.scheduler.proxy"] = "true";
properties["quartz.threadPool.threadCount"] = "0";
properties["quartz.scheduler.proxy.address"] = address;

To answer such questions it's easier to just look at source code of method in question (if possible). If you look at source code for Interrupt, you will see approximately this:

public virtual bool Interrupt(JobKey jobKey)
{
  var currentlyExecutingJobs = this.CurrentlyExecutingJobs;
  bool interruptedAny = false;
  foreach (var executionContext in currentlyExecutingJobs)
  {
    var jobDetail = executionContext.JobDetail;
    if (jobKey.Equals((object) jobDetail.Key))
    {
      var interruptableJob = executionContext.JobInstance as IInterruptableJob;
        if (interruptableJob != null) {
            interruptableJob.Interrupt();
            interruptedAny = true;
        }
        else {
            // throws here
        }
    }
  }
  return interruptedAny;
}

So it enumerates all current jobs and interrupts any with the matching JobKey (which by the way makes checks in your code unnecessary - you can just do scheduler.Interrupt(jobKey)). So unless all your jobs somehow have matching key - it should not delete them all.

I apologize but I finally found the issue on my end. It turned out to be a misconfiguration with my registration code using a NInjectJobFactory.

Basically, there was only a single job instance running for each job execution so the flag I was setting to stop the job being interrupted was shared amongst all job executions, thereby stopping all the jobs!
