Telnet failure to localhost is expected and is unrelated since servers
are not listening on it.
What is the ip address of this machine?
Try 'telnet different_datanode_ip 50010' _from_ this machine. What do
you see?

Hi.
Shouldn't you be testing connecting _from_ the datanode? The error you
posted is while this DN is trying connect to another DN.
You might be into something here indeed:
1) Telnet to 192.168.253.20 8020 / 192.168.253.20 50010 works
2) Telnet to localhost 8020 / localhost 50010 doesn't work
3) Telnet to 127.0.0.1 8020 / 127.0.0.1 50010 doesn't work
In the 2 last cases I get:
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
Could it be related?
Regards.
