Hi all, 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, Thanks, Masoud
