I am working to setup a small cloud of 8 nodes. All slave nodes are attached to a standalone switch. The master node, which has zookeeper, namenode and jobtracker has two nics: one on the standalone switch and one to the main network.
I was hoping that I could run java code to query the cloud through the master from any system on the main network. Is this possible or will I have to run the code on the master node with this setup? Currently I am getting this error:
ZooKeeperInstance zki = new ZooKeeperInstance("cloud", "master-server");
System.err.println("Got zookeeper instance!");
Connector conn = zki.getConnector("root", "somepassword");
System.err.println("never get here.");

Thanks in advance,
