Hi Andy, thank you for info. But we do not need to use SSH if my client has no problem to communicate with NN and TN right?
Also, I notice that this eclipse plugin always send my windows account name to access HDFS. it keeps doing same thing even I change the eclipse.plug-inuser.name in teh DFS edition panel. Do you know if the problem from plugin itself or eclipse? thank you!
