Hi, I asked this question at stackoverflow.
In my case, Spring Rest API embed ignite, that API is act as cache. There
are only Put/Get API, and they put to /get from Ignite caches.
My total Configuration like below(Java Code)
IgniteConfiguration config = new IgniteConfiguration();
//discovery : multicast, I set consistentId manually for easily
Identifying me, actually I set named node1, node2, node3
config.setRebalanceThreadPoolSize(3);
config.setConsistentId(uniqueNodeId);
//3caches, Partitioned,
config.setCacheConfiguration(
new CacheConfiguration<K, V>()
.setName(name1)
.setBackups(1)
.setCacheMode(PARTITIONED)
.setWriteSynchronizationMode(PRIMARY_SYNC)
.setCopyOnRead(false),
new CacheConfiguration<K, V>()
.setName(name2)
.setBackups(1)
.setCacheMode(PARTITIONED)
.setWriteSynchronizationMode(PRIMARY_SYNC)
.setCopyOnRead(false),
new CacheConfiguration<K, V>()
.setName(name3)
.setBackups(1)
.setCacheMode(PARTITIONED)
.setWriteSynchronizationMode(PRIMARY_SYNC)
.setCopyOnRead(false))
//pageSize : 4096, enable persistent, initRegionSize/maxRegionSize : 2G
config.setDataStorageConfiguration(new DataStorageConfiguration()
.setPageSize(4096)
.setMetricsEnabled(false)
.setDataRegionConfigurations(new DataRegionConfiguration()
.setPersistenceEnabled(true)
.setName("myName")
.setInitialSize(2147483648)
.setMaxSize(2147483648)
.setPageEvictionMode(DataPageEvictionMode.DISABLED)
.setMetricsEnabled(false)));
//event listening, for monitoring
int [] listenedEvent = {
EventType.EVT_CACHE_NODES_LEFT,
EventType.EVT_CACHE_OBJECT_PUT,
EventType.EVT_CACHE_REBALANCE_STARTED,
EventType.EVT_NODE_JOINED
};
config.setIncludeEventTypes(listenedEvent);
config.setLocalEventListeners(new HashMap<IgnitePredicate<? extends
Event>, int[]>() {{
put(event -> {
LOGGER.info("Event - time : {}, name : {}, type : {}, msg: {},
nodeId : {}",
LocalDateTime.ofInstant(Instant.ofEpochMilli(event.timestamp()),
ZoneId.systemDefault()),
event.name(), event.type(), event.message(), event.node().id());
return true;
}, listenedEvent);
}});
then, when I started tomcat, below is my ignite log/I checked here,
persistentEnabled true and 3 nodes are all joined.

Then I shut down node2 for restart(in node2)
$>service tomcat stop
As soon as stopping tomcat node2, below log is written at node1, 3

I don't know what is wrong.
please consider, I am newbie ignite. I hope to your help
