Starting Server node on a cluster through Service and trying loadcache - ignite

Question

I debugged the code and found all parameters being set appropriately and even in the console we can see that the server in remote node has started and the cache has been initialized.
All the requried parameters are passed through db
On trying to assert on the cache wihtout lazyload(hotloading it from the persistent store) the error log that i get is ,
I am not able to understand what s going wrong in the cluster so have only attached the code that does the job of starting the servers.
InitializeCache internally calls loadcache after all the keyfileds,jdbctypes are set..
class{
private void startNodes() {
logger.info("Starting Ignite Nodes");
IgniteCluster igniteCluster = rocCachemanager.getCluster();
// HashMaps for holding host and default configurations
HashMap<String, Object> defaults = new HashMap<>();
HashMap<String, Object> hmHosts;
// get Ignite configuration from DB
List<IgniteConfigPojo> list = igniteConfigImpl.getIgniteConfigList();
IgniteConfigPojo configPojo = list.get(0);
List<IgniteNodeMapPojo> listNodeMap = configPojo.getIgniteNodeMap();
// Collection of Host configuration
Collection<Map<String, Object>> hosts = new ArrayList<>();
// Prepare the map with all the ignite server host information
prepareHostList(listNodeMap, hosts);
// Actual start of remote nodes via ssh call
try {
if (listNodeMap.size() != igniteCluster.forServers().nodes().size()) {
Collection<ClusterStartNodeResult> result = igniteCluster.startNodes(hosts, defaults, false, 10000, 1);
for (ClusterStartNodeResult res : result) {
if (!res.isSuccess()) {
throw new ROCCacheException(res.getError());
} else {
logger.info("Ignite server start successfully triggered on machine " + res.getHostName());
}
}
}
int waitTime = 0;
while (listNodeMap.size() != igniteCluster.forServers().nodes().size()) {
if (waitTime >= MAX_TIME_FOR_SERVER_START) {
int serverNodes = igniteCluster.forServers().nodes().size();
throw new ROCCacheException("All the Server nodes have not joined the Ignite Cluster, Expected servers :"
+ listNodeMap.size() + " , actual :" + serverNodes);
}
synchronized (this) {
wait(2000);
}
waitTime += 2000;
}
logger.info("Successfully started all the ignite servers");
} catch (IgniteException e) {
throw new ROCCacheException("Error while starting the Ignite Servers", e);
} catch (InterruptedException e) {
