The code bellow let you read the data of a zNode.

Calling the method "CuratorFramework::getData" will return a "byte[]" array.

You will get this error if the zNode doesn't exist in ZooKeeper: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode 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 read the data of a 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::getData final String path = "/abc"; final byte[] data = curatorFramework.getData().forPath(path); // -- CuratorFramework::close curatorFramework.close();
