I am running a simple code to test Apache Ignite distributed cache. One node
is on a server and the other one is run locally when I start a java program.
public class HelloIgnite {
public static void main(String[] args) {
System.out.println("Hello Ignite");
Ignite ignite = Ignition.start("example-cache.xml");
// get or create cache
IgniteCache<Integer, String> cache =
ignite.getOrCreateCache("testCache");
// put some cache elements
for(int i = 1; i <= 100; i++){
cache.put(i, Integer.toString(i));
}
// get them from the cache and write to the console
for(int i =1; i<= 100; i++){
System.out.println("Cache get:"+ cache.get(i));
}
ignite.close();
}
}
The above is the simple code I am testing. And here is my ignite config
<beans xmlns="http://www.springframework.org/schema/beans";

xsi:schemaLocation="

I start node on the server using ignite.sh -p example-cache.xml first and
then run the above code locally. However, instead of putting values to the
cache and printing them, when I run the code, it is stuck showing this
message:
/ [13:40:46] Configured failure handler: [hnd=StopNodeOrHaltFailureHandler
[tryStop=false, timeout=0, super=AbstractFailureHandler
[ignoredFailureTypes=[SYSTEM_WORKER_BLOCKED,
SYSTEM_CRITICAL_OPERATION_TIMEOUT]]]]
[13:40:48] Message queue limit is set to 0 which may lead to potential OOMEs
when running cache operations in FULL_ASYNC or PRIMARY_SYNC modes due to
message queues growth on sender and receiver sides.
[13:40:49] Security status [authentication=off, tls/ssl=off]/
On the node I started on the server, It is repeatedly printing the following
to the console:
/[11:48:28] Topology snapshot [ver=56, locNode=cd55466e, servers=2,
clients=0, state=ACTIVE, CPUs=40, offheap=28.0GB, heap=34.0GB]
[11:48:28] Topology snapshot [ver=57, locNode=cd55466e, servers=1,
clients=0, state=ACTIVE, CPUs=32, offheap=25.0GB, heap=30.0GB]
[11:48:34] Joining node doesn't have encryption data
[node=02e2f398-b5b8-4044-83dd-53755e28f94e]/
However, when I stop the server node, the local node starts to run properly
and print the values.
How can I resolve this? what I am doing wrong here?
