I am not sure if it helps - please note that:
- loadCache() shall be called once. Call it on a client node and not on the server nodes. What loadCache() does it just broadcasts request to invoke CacheStore's loadCache() on every server node. - loadCache() is optional - you use it if you want to "warm up" the data. You still can start without calling loadCache() having no pre-loaded data. - First start the cluster and wait your final topology. Then connect a client utility that would call loadCache().
