I am getting the following error when running a code with IgniteAtomicLong
counter:
Exception in thread "main" class org.apache.ignite.IgniteException: Failed

The CounterApplication:
public class CounterApplication {
public static void main(String[] args) throws InterruptedException {
try (final Ignite ignite = Ignition.start()) {
final IgniteAtomicLong counter = ignite.atomicLong("myCounter",
0, true);
System.out.println("Waiting 5 seconds...");
sleepMillis(5_000);
System.out.println("Starting to count...");
IntStream.range(0, 10_000).forEach(n -> {
sleepMillis(1);
counter.incrementAndGet();
});
}
}
private static void sleepMillis(final int millis) {
try {
Thread.sleep(millis);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
}
}
In order to reproduce the problem, start two instances of
CounterApplication, and after the second instance join the grid, kill the
other.
Waiting 5 seconds...
