String parent = new Path(leaderPath).getParent().toString();

synchronized (lock) {
log.info("Creating leader registration node {} after winning as {}", leaderPath, leaderSeqPath);
List<Op> ops = new ArrayList<>(2);    //here should be 3 or more

// We use a multi operation to get the parent nodes version, which will
// be used to make sure we only remove our own leader registration node.
// The setData call used to get the parent version is also the trigger to
// increment the version. We also do a sanity check that our leaderSeqPath exists.

ops.add(Op.check(leaderSeqPath, -1));
ops.add(Op.create(leaderPath, Utils.toJSON(leaderProps), zkClient.getZkACLProvider().getACLsToAdd(leaderPath), CreateMode.EPHEMERAL));
ops.add(Op.setData(parent, null, -1));
List<OpResult> results;

results = zkClient.multi(ops, true);
