Saving file in SAS EG


When I try to save/copy files via hadoop from SAS EG, I'm getting the following error:


ERROR: Call From servername/serverIPaddress to 
servername1:8020 failed on socket timeout exception: 
20000 millis timeout while waiting for channel to be ready for connect. ch : 
java.nio.channels.SocketChannel[connection-pending remote=servername1/server1IPaddress:8020];

 What can be the problem?

Looks like it is trying the wrong ip or socket - check if you have the correct ones.

What are you trying to do?
Please show the full log.
Can this be reproduced by other files, programs and clients?

I know surely you must be following the two basic things.

--> the user bt which the operation is performed should be have a passwordless ssh connection to the datanodes.

--> Second you can check for the datanaode status from the 50070 port. Maybe the hadoop services need to be restarted.
                    --> in putty login from user which has password ssh access to datanodes.

                    --> establish ssh connection to datanode.
                    --> execute the /Hadoop/hadoop-2.4.0/sbin/


If the above is in perfect order then you have to provide more details on the log.
