Hi Andrey,
Thank you very much for the prompt response.
We have only one node in a JVM.
This is my grid config. We use 1.9.0 Ignite.
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setPeerClassLoadingEnabled(false);
cfg.setLifecycleBeans(new LogLifecycleBean());
TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi();
TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
Collection<String> addressSet = new HashSet<>();
for (String address : ipList) {
addressSet.add(address);
}
ipFinder.setAddresses(addressSet);
discoverySpi.setJoinTimeout(10000);
discoverySpi.setLocalPort(47500);
discoverySpi.setIpFinder(ipFinder);
cfg.setDiscoverySpi(discoverySpi);
And this is the cache config. We don’t set cache group specifically.
CacheConfiguration<String, String> cc = new CacheConfiguration();
cc.setName("mycache");
cc.setBackups(1);
cc.setCacheMode(CacheMode.PARTITIONED);
cc.setAtomicityMode(CacheAtomicityMode.ATOMIC);
LruEvictionPolicy evpl = new LruEvictionPolicy();
evpl.setMaxSize(10000);
cc.setEvictionPolicy(evpl);
cc.setExpiryPolicyFactory(CreatedExpiryPolicy.factoryOf(
new Duration(TimeUnit.SECONDS, 15)));
cc.setStatisticsEnabled(true);

Hi,
Looks like a bug.
Can you share grid configuration?
Do you have more than one node in same JVM?
Do you have configure cache groups manually?

Hi everyone,
As a quick note on what we do here, we listen to NODE_FAILED, and
NODE_SEGMENTED events and upon such events, we use Ignition.stopAll(true) and
Ignition.start() to restart the Ignite grid in a given JVM. Here Ignite does
not starts as a standalone process by itself, but bootstrap programmatically
since it’s meant to be a part of some other main process.
So we received a NODE_FAILED evet and restarted Ignite where we see following
error and start fails. And “mycache” is created with LRU eviction policy at
Ignite startup process.
As per error, it tries to registering an LruEvictionPolicy MBean twice. We use
a cache named mycache in PARTITIONED mode with 4 nodes in the cluster. Any idea
for this behavior ?
