Description:
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
{code}
private def startScheduler() = {
ignite.scheduler.scheduleLocal(new Runnable() {
override def run() =
try {
Logger.info("Tick tock")
/** Do Stuff! */
}
catch { case e:Exception => Logger.error("I poked, I failed!", e) }
}, "* * * * *")}
{code}
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) :
{code}
/** {@inheritDoc} */
@Override public void start() throws IgniteCheckedException {
sched = new Scheduler();
sched.start();
}
{code}
That's why the default (empty) impl is used. And the "sched" attribute stay
null.
