> Issue Type: Bug
> Affects Versions: 2.0
> Environment: Oracle Hotspot 1.8_121
> Ignite 2.0.0
> Springmix 4.3.7
> Reporter: Mikhail Cherkasov

> NPE occurs during deploying a service as cluster singleton. Ignite scheduler is used as a cron for this purpose, however NPE occurs for ignite version 2.0.0.
> Below is the log information for the exception:

> This exception occurs right on start up when try to add a services to the cron.
> The scheduler from example us used: https://apacheignite.readme.io/docs/cron-based-scheduling .
> Below is the example, similar to the issue raised by another user, link for the reference (http://apache-ignite-users.70518.x6.nabble.com/Fwd-NPE-at-ScheduleFutureImpl-line-177-td13435.html

> I think the scheduler processor does not match the expected processor
> interface. This results to a bad state.
> IgniteKernal is responsible to start each processors :
> org.apache.ignite.internal.IgniteKernal.startProcessor(GridProcessor):
> proc.start(cfg.isActiveOnStart());
> But the
> org.apache.ignite.internal.processors.schedule.IgniteScheduleProcessor does
> not implement it (missing boolean parameter) :
> /** {@inheritDoc} */
> @Override public void start() throws IgniteCheckedException {
> sched = new Scheduler();
> sched.start();
> }
> That's why the default (empty) impl is used. And the "sched" attribute stay
> null.
