Hi,
I am deploying a webapp, which internally queries elasticsearch. I am
creating only one connection, and I want to close it when the webapp shuts
down. I am using singleton pattern for creating the ES client and how do I
destroy/close ES client? When the application shuts down, will the client
get closed or I have to specify it/ where should I have the code to close
the connection?
This is my code:
```
public class ESClientManager {
public static Client client = null;
private static Settings settings = null;
private static Object mutex = new Object();
private static final String CONFIG_CLUSTER_NAME = "cluster.name";
private static final String CLUSTER_NAME = "qatool_es";
private static final String[] transportAddress = {
"127.0.0.1"
};
private static final int transportPort = 9300;
private ESClientManager() {
}
public static Client getClient() {
if (client == null) {
synchronized (mutex) {
settings = ImmutableSettings.settingsBuilder()
.put(CONFIG_CLUSTER_NAME, CLUSTER_NAME).build();
client = new TransportClient(settings);
for (int i = 0; i < transportAddress.length - 1; i++) {
((TransportClient) client).addTransportAddress(new
```
InetSocketTransportAddress(transportAddress[i], transportPort));
}
logger.info("Elastic search client initialized");
}
}
logger.info("Returning the existing client");
return client;
}
}

Have you try using client.close() ?
