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

To set the ACL of a zNode you have to define:
► The ACL Scheme: "world", "auth", "digest", "ip".
► The ACL Scheme Id: for example, the scheme "world" has a single Id "anyone".
► The ACL permissions: "ALL", "ADMIN", "CREATE", "DELETE", "READ", "WRITE".

Calling the method "CuratorFramework::setACL" will initialize the ACL 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$NoNodeException: KeeperErrorCode = NoNode for /path
You will get this error if the ACL is invalid: org.apache.zookeeper.KeeperException$InvalidACLException: KeeperErrorCode = InvalidACL for /path
You will get this error if you don't have permissions to set the ACL of a zNode: org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth 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 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::setACL final String path = "/abc"; // using scheme:id:perms syntax final List<ACL> acls = AclParser.parse("ip:127.0.0.1:cdraw,world:anyone:rwcda"); // using ACL class { final ACL acl = new ACL(); acl.setId(new Id("ip", "127.0.0.2")); acl.setPerms(ZooDefs.Perms.ALL); // acl.setPerms(ZooDefs.Perms.READ); // acl.setPerms(ZooDefs.Perms.WRITE); // acl.setPerms(ZooDefs.Perms.CREATE); // acl.setPerms(ZooDefs.Perms.DELETE); // acl.setPerms(ZooDefs.Perms.ADMIN); acls.add(acl); } final Stat stat = curatorFramework.setACL().withACL(acls).forPath(path); System.out.println(stat); // -- CuratorFramework::close curatorFramework.close();
