I believe it needs to be prefixed with "zk://" rather than zoo.
The relevant code is in detector.cpp:
* } else if (master.find("zk://") == 0) {*
Try<zookeeper::URL> url = zookeeper::URL::parse(master);
if (url.isError()) {
return Error(url.error());
}
if (url.get().path == "/") {
return Error(
"Expecting a (chroot) path for ZooKeeper ('/' is not supported)");
}
return new ZooKeeperMasterDetector(url.get(), pid, contend, quiet);
}
