Hi,
I am trying to use apache ignite cache for the first time. I have 2 java
spring boot applications, the first one is configured as an ignite server:
Snippet from ignite-config-dev.xml:
<property name="clientMode" value="false"/>
And it is creating a cache on start -up:
public void initCache() {
Ignite ignite = Ignition.start(igniteConfiguration.
getIgniteConfigurationFilename());
CacheConfiguration cfg = new CacheConfiguration("IMAGE_CACHE");
cache = ignite.getOrCreateCache(cfg);
}
The application also inserts some objects into the cache which i would like
to read from the second application.
The second java application is started as an ignite client:
Snippet from ignite-config-dev.xml:
<property name="clientMode" value="true"/>
And it trys to get the cache created by the server:
Ignite ignite = Ignition.start(igniteConfiguration.
getIgniteConfigurationFilename());
CacheConfiguration cfg = new CacheConfiguration("IMAGE_CACHE");
cache = ignite.getOrCreateCache(cfg);
However, it looks like the call to getOrCreateCache in the client is
creating a new cache rather than accessing the one created by the server.
When the server starts up i see the following in the logs:

>From looking at the logs (and from using a debugger during client start up)
it seems to me that the client has discovered the server but is creating a
new cache and not seeing the one created by the server.
Any suggestions on where i might be going wrong with my configuration?
Thanks,
Maureen
