I have been happily working with Acc, but today things changed.  No errors

Until now I ran everything server side, which meant the URL was
localhost:2181, and life was good.  Today tried running some of the same
code as a remote client, which means <host name>:2181.  Things hang when
BatchWriter tries to commit anything and Scan hangs when it tries to
iterate through a Map.

Let's focus on the scan part:

scan.fetchColumnFamily(new Text("colfY")); // This executes then hangs.
for(Entry<Key,Value> entry : scan) {
def row = entry.getKey().getRow();
def value = entry.getValue();
println "value=" + value;
}

This is what appears in the console :

17:22:39.802 C{0} M DEBUG org.apache.zookeeper.ClientCnxn - Got ping
response for sessionid: 0x148c6f03388005e after 21ms

17:22:49.803 C{0} M DEBUG org.apache.zookeeper.ClientCnxn - Got ping
response for sessionid: 0x148c6f03388005e after 21ms

<and on and on>


The only difference between success and a hang is a URL change, and of
course being remote.

I don't believe this is a firewall issue.  I shutdown the firewall.

Am I missing something?

Thanks all.
