The code bellow let you set the data of a zNode if its data version matches the specified version.

Calling the method "CuratorFramework::setData" will initialize the data of a zNode and return a "Stat" object.

You will get this error if the zNode doesn't exist in ZooKeeper: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /path
You will get this error if the version of the zNode (dataVersion) is incorrect: org.apache.zookeeper.KeeperException$BadVersionException: KeeperErrorCode = BadVersion 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 set the data of a zNode if its data version matches the specified version:
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::setData::withVersion final String path = "/abc"; final String data = "zNode data ..."; final int version = 1; final Stat stat = curatorFramework.setData().withVersion(version).forPath(path, data.getBytes()); System.out.println(stat); // -- CuratorFramework::close curatorFramework.close();
