Subject Re: cannot connect from slaves
Date Fri, 14 Jan 2011 02:49:42 GMT
I did this, and tried both ways:

hadoop fs -ls /
11/01/14 02:45:25 INFO ipc.Client: Retrying connect to server: /
10.113.118.244:8020. Already tried 0 time(s).
11/01/14 02:45:29 INFO ipc.Client: Retrying connect to server: /
10.113.118.244:8020. Already tried 1 time(s).

and

hadoop fs -ls hdfs://10.113.118.244/
11/01/14 02:48:56 INFO ipc.Client: Retrying connect to server: /
10.113.118.244:8020. Already tried 0 time(s).

I am suspecting the port 8020 - how do I test it outside of hadoop?

Thank you,
Mark
