title: Ignite Remote Cluster [Failed to map keys for cache (all partition nodes left the grid)]
body: <p>I am having some issues creating cache K,V pairs on my remote Ignite cluster. My Ignite nodes are built on a Maven project in Java8, clustered via multicast configuration, with partitioned cache. The problem faced here is that ignite can only successfully create and retrieve cache via SqlFieldQuery or NoSQL when there are exactly 1 node in the cluster. When I scale it to more than 1(in this case 2), I face this error thrown by the remote server.</p>

  <p>Data insertion is using the simple  cache.put command. Appreciate if anyone can help me out on this.</p>
