Accumulo tservers typically listen on a single interface. If= you have a server with multiple interfaces (e.g. loopback and eth0), you m= ight have a problem in which the tablet servers are not listening on extern= ally reachable interfaces. Tablet servers will list the interfaces that the= y are listening to when they boot, and you can also use tools like lsof to = find them.

If that is indeed the problem, then you might just need to c= hange you conf/slaves file to use <hostname> instead of localhost, an= d then restart.

Let's focus on the scan part:

scan.fetchColumnFa= mily(new Text("colfY")); // This executes then hangs.
<= span style=3D"white-space:pre-wrap"> for(Entry<Key,Value> entr= y : scan) {
def= row =3D entry.getKey().getRow();
def value =3D entry.getValue();
println "value=3D" + value;
=
}

This is what appears in the console :

<= p style=3D"margin:0px;font-size:11px;font-family:Monaco">17:22:39.802 C{0} M DEBUG org.apache.zookeeper.ClientCnxn - Got ping = response for sessionid: 0x148c6f03388005e after 21ms

<and on and o= n>

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

I don't be= lieve this is a firewall issue.=C2=A0 I shutdown the firewall.
Am I missing something?

Thanks all.
