Re: remote accumulo instance issue
These are from the client machine:
(9997 on a tserver)
[mreichman@packers: ~]$ nmap -p 9997 192.168.1.162

Starting Nmap 5.51 ( http://nmap.org ) at 2013-05-08 16:35 ric
Nmap scan report for giants.home (192.168.1.162)
Host is up (0.0063s latency).
PORT     STATE SERVICE
9997/tcp open  unknown
MAC Address: 7A:79:C0:A8:01:A2 (Unknown)

Nmap done: 1 IP address (1 host up) scanned in 0.60 seconds

(2181 zookeeper on the master)
[mreichman@packers: ~]$ nmap -p 2181 192.168.1.160

Starting Nmap 5.51 ( http://nmap.org ) at 2013-05-08 16:35 ric
Nmap scan report for padres.home (192.168.1.160)
Host is up (0.0071s latency).
PORT     STATE SERVICE
2181/tcp open  unknown
MAC Address: 7A:79:C0:A8:01:A0 (Unknown)

Nmap done: 1 IP address (1 host up) scanned in 0.56 seconds

Any chance it could be anything related to DNS or reverse DNS?
