Hi all,

I meet a wried problem that I can not access hadoop cluster from outside. I
have a client machine, and I can telnet namenode's port 9000 in this client
machine , but I can not access the namenode through command  "hadoop fs
10.249.68.39:9000 -ls /"

It tells me "Bad connection to FS. command aborted. exception: Call to /
10.249.68.39:9000 failed on local exception: java.io.IOException: Connection
reset by peer"

Has anyone meet this problem before ? I guess maybe some network
configuration problem, but not sure what's wrong. Thanks

What is your ${fs.default.name} set to?

Jeff,
I would first double check if port 9000 is your service rpc port.  If yes, give a try to,

hadoop fs -fs hdfs://10.249.68.39:9000 -ls /

Tanping

I find the reason. This is because I use different version of hadoop between
server side and client. Seems CDH is not compatible with
apache release version
