laves could not connect on 9000 and 9001 ports of master

[Masoud]

Hi all,

we have this problem:
org.apache.hadoop.ipc.Client: Retrying connect to server: 
master/*.*.*.*:9000. Already tried 0 time(s).

and for 9001 is same problem too, we opened these port on master firewall.
We use NAT to setup our Linux network.

Let me know your ideas,

Thanks,
Masoud
