> When trying to delete a job from a recurrent job queue, Helix throws NPE if the job does not exist in last scheduled workflow.
> java.lang.IllegalArgumentException: Could not remove job BackupJob_MailboxDB from DAG of queue BackupJobQueue_ESPRESSO_CHO_1_SCHEDULED_0
> at org.apache.helix.task.TaskDriver.removeJobFromDag(TaskDriver.java:411)
> at org.apache.helix.task.TaskDriver.deleteJobFromScheduledQueue(TaskDriver.java:345)
> at org.apache.helix.task.TaskDriver.deleteJob(TaskDriver.java:303)
> It is possible for a user to add and immediately delete the job before the next workflow is scheduled. Helix should accommodate this case and check if the job exists in last scheduled workflow before trying to delete it.
