> Task framework expects the "Task" state model to be already defined. Otherwise enqueueing a job using ClusterTask framework throws this exception:
> org.apache.helix.HelixException: State model Task not found in the cluster STATEMODELDEFS path
> 	at org.apache.helix.manager.zk.ZKHelixAdmin.addResource(ZKHelixAdmin.java:608)
> 	at org.apache.helix.manager.zk.ZKHelixAdmin.addResource(ZKHelixAdmin.java:651)
> 	at org.apache.helix.manager.zk.ZKHelixAdmin.addResource(ZKHelixAdmin.java:625)
> 	at org.apache.helix.manager.zk.ZKHelixAdmin.addResource(ZKHelixAdmin.java:592)
> 	at org.apache.helix.task.TaskDriver.scheduleJob(TaskDriver.java:327)
> 	at org.apache.helix.task.TaskDriver.enqueueJob(TaskDriver.java:316)
> 	at com.linkedin.espresso.bulkmigrator.BulkOperationScheduler.schedule(BulkOperationScheduler.java:98)
> 	at com.linkedin.espresso.test.bulkoperation.ScheduleEIJob.main(ScheduleEIJob.java:38)
> Existing clusters will not have "Task" state model already defined. It would be really great if the task framework automatically creates it if the state model doesn't exist.
