The code bellow let you create a zNode under a specific path and assigning data to the zNode.

Calling the method "CuratorFramework::create" will return the path of the created zNode.

You will get this error if the parent zNode doesn't exist in ZooKeeper:

org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /path

You will get this error if the zNode exists in ZooKeeper:

org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode = NodeExists for /path

In order for the code bellow to work:
► Make sure to update the "CONNECT_STRING" variable with your information.

Here's an example of how to create a zNode under a specific path + assigning data to the zNode:

final String CONNECT_STRING = "localhost:2181";

final int SESSION_TIMEOUT_MS = Integer.valueOf(60 * 1000);
final int CONNECTION_TIMEOUT_MS = Integer.valueOf(15 * 1000);
final RetryPolicy RETRY_POLICY = new RetryOneTime(1000);

// -- CuratorFrameworkFactory::newClient
final CuratorFramework curatorFramework = CuratorFrameworkFactory.newClient(CONNECT_STRING, SESSION_TIMEOUT_MS, CONNECTION_TIMEOUT_MS, RETRY_POLICY);

// -- CuratorFramework::start
curatorFramework.start();

// -- CuratorFramework::create::forPath(path, data)
final String path = "/abc";
final String data = "zNode data ...";
final String result = curatorFramework.create().forPath(path, data.getBytes());

System.out.println(result);

// -- CuratorFramework::close
curatorFramework.close();
