Is DynoClient Supports Single ton Implementation

I build a dynomite cluster of 3 racks. Each rack consists of two nodes.
I implemented dyno client for Java. I used singleton Implementation. if one of the node is getting down. then I am observed errors of peer not connected. if I again establish the connection when one of the node get down. it works properly

`public static DynoJedisClient establishingConnection() {

DynoJedisClient dynoclient = null;
String client = Configuration.getProperty(CacheConstants.DYNOMITE_CLIENT, "dynomiteclient");
String cluster = Configuration.getProperty(CacheConstants.DYNOMITE_CLUSTER, "dynomitecluster");
String seeds = Configuration.getProperty(CacheConstants.DYNOMITE_SEEDS, "RedisMaster:192.168.56.221:8102:rack1:dc1:0|RedisSlave01:192.168.56.222:8102:rack2:dc1:0|RedisSlave02:192.168.56.223:8102:rack3:dc1:0");
System.out.println(seeds);
List<DynomiteNodeInfo> nodes = DynomiteSeedsParser.parse(seeds);
ArchiesProperties properties = DynomiteProperties.setProperties(client, seeds, 10, 3000,3,2000);
dynoclient = new DynoJedisClient.Builder()
		.withApplicationName(client)
		.withDynomiteClusterName(cluster)
		.withCPConfig(new ArchaiusConnectionPoolConfiguration(client)
				.withTokenSupplier(properties.getTokenMapSupplier())
				.setMaxConnsPerHost(properties.getMaxConnectionPerHost())
				.setConnectTimeout(properties.getConnectionTimeout()))
		.withHostSupplier(TokenMapSupplierHelper.toHostSupplier(nodes))
		.build();
return dynoclient;

}``

single ton implementation

public static DynoJedisClient build() {
DynoJedisClient dynoClient = dynoJedisClient.get(module);
if (dynoJedisClient.get(module) == null) {
synchronized(DynomiteConnection.class) {
if (dynoJedisClient.get(module) == null) {
dynoClient = establishingConnection() ;
dynoJedisClient.put(module,dynoClient);
}
}
}
return dynoClient;
}

please give any examples or links for singleton Implementation of dyno client

@chinmayvenkat I don't understand your issue properly. If a node is down, you won't be able to talk to it and you'll fallback to a different replica which you say works correctly. The DynoJedisDemo has implementations of how to use the Dyno client:
