Hi Prasad,
The root cause of IllegalStateException you observed is that the Ignite
instance is created within IgniteSpringBean#afterSingletonsInstantiated()
method which is triggered by the Spring Framework.
So, you should not call ignite.active(true) method here:
@Bean
public IgniteSpringBean igniteInstance() {
IgniteSpringBean ignite = new IgniteSpringBean();
// Please do not call active() method here
// Ignite instance is not initialized yet.
//ignite.active(true);
ignite.setConfiguration(getIgniteConfiguration());
return ignite;
}
One possible workaround is using Ignite LifecycleBeans [1]
// Lifecycle bean that activates the cluster.
public class MyLifecycleBean implements LifecycleBean {
@IgniteInstanceResource
private Ignite ignite;
@Override public void onLifecycleEvent(LifecycleEventType evt) {
if (evt == LifecycleEventType.AFTER_NODE_START) {
ignite.active(true);
}
}
}
// Provide lifecycle bean to the configuration.
private IgniteConfiguration getIgniteConfiguration() {
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setLifecycleBeans(new MyLifecycleBean());
...
return cfg;
}
