Subject: Acl block detete not working Hi,
I'm using 3.4.10 and setting custom aol to block deletion of a znode.  However, I'm able
to delete the node even after I've set acl from cdrwa to crwa.
Can anyone point out if I missed some step.
Thanks for the help

Here is the trace:

MG>in SetAclCommand you can see the acl being parsed and acl being set by setAcl into
zk object
    List<ACL> acl = AclParser.parse(aclStr);        int version;        if
(cl.hasOption("v")) {            version = Integer.parseInt(cl.getOptionValue("v")); 
      } else {            version = -1;        }        try {       
    Stat stat = zk.setACL(path, acl, version);
MG>later on in DeleteCommand there is no check for aforementioned acl parameter   public
boolean exec() throws KeeperException, InterruptedException {        String path = args[1]; 
      int version;        if (cl.hasOption("v")) {            version = Integer.parseInt(cl.getOptionValue("v")); 
      } else {            version = -1;        }                try
{        zk.delete(path, version);        } catch(KeeperException.BadVersionException
ex) {            err.println(ex.getMessage());        }        return false;
MG>as seen here the testCase works properly saving the Zookeeper object     LsCommand
entity = new LsCommand();        entity.setZk(zk);

MG>but setACL does not save the zookeeper object anywhere but instead seems to discard
zookeeper object with accompanying ACLsMG>can you report this bug to Zookeeper?
