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

Calling the method "CuratorFramework::getACL" will return a "List<ACL>" list.

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 ACL 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::getACL
final String path = "/abc";

final List<ACL> acls = curatorFramework.getACL().forPath(path);

if (acls != null) {
    for (ACL acl : acls) {
        System.out.println("acl: " + acl);
    }
}

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