Re: Can not access hadoop cluster from outside

2011-06-02 Thread Jeff Zhang 
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

 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 /

 Subject: Can not access hadoop cluster from outside

 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
