we made a pilot cluster in 3 machines and testing some accepts of hadoop.
now trying to setup hadoop on 32 nodes, the problem is below:
org.apache.hadoop.ipc.Client: Retrying connect to server:
master/*.*.*.*:9000. Already tried 0 time(s).
and even for 9001, we opened these port on master.
We use NAT to setup our Linux network.
Let me know your ideas,
