Hi all,
I have tried to construct a cluster with two nodes.
my run environment
==============================================================================================
OS: Ubuntu 14.04.5 LTS
Java version: 1.7
Ignite version: 1.9.0
===============================================================================================================
One node with a “example-cache.xml” was triggered by the shell script as the
following command:./bin/ignite.sh config/example-cache.xml
The execution results of the program is as:
shell script result
================================================================================================
Local node [ID=D411C309-E56A-4773-ABD1-132ADE62C325, order=1, clientMode=false]
Local node addresses: [ubuntu/0:0:0:0:0:0:0:1%lo, /127.0.0.1]
Local ports: TCP:8080 TCP:11211 TCP:47100 UDP:47400 TCP:47500

[25-01-2018 15:23:48][INFO ][Thread-23][GridCacheProcessor] Stopped cache:
oneCache
===============================================================================================================
The other node was triggered by the maven project (java 1.7) as the following
command: mvn compile exec:java -Dexec.mainClass=…
In addition, my java code is as:
Java code
======================================================================================================
TcpDiscoveryMulticastIpFinder ipFinder = new TcpDiscoveryMulticastIpFinder();
TcpDiscoverySpi spi = new TcpDiscoverySpi();
spi.setIpFinder(ipFinder);
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(false);
cfg.setDiscoverySpi(spi);
Ignite igniteVar = Ignition.getOrStart(cfg);
CacheConfiguration cacheConf = new CacheConfiguration();
cacheConf.setName("oneCache");
cacheConf.setIndexedTypes(String.class, String.class);
IgniteCache cache = igniteCache.getOrCreateCache(cacheConf);
===============================================================================================================
The execution results of the java program is as:
Maven project(java) result
=========================================================================================

SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
Program execution lock….
===============================================================================================================
And, If I closed One node(shell script), the Maven project program started
running, as:

===============================================================================================================
I have no idea to connect both nodes and share the same oneCache under the
above situation.
If any further information is needed, I am glad to be informed and will provide
to you as soon as possible.
I am looking forward to hearing from you.
