Subject Re: Anybody know how to configure SSH for eclipse plugin
Date Tue, 27 Nov 2012 20:39:15 GMT
hi Harsh,

thank you for helps! I think I was blur yesterday. But, it is partly
misleaded by the comments in  HadoopServer.java file


 * <p>
 * This class does not create any SSH connection anymore. Tunneling must be
 * setup outside of Eclipse for now (using Putty or <tt>ssh -D&lt;port&gt;
 * &lt;host&gt;</tt>)
 *

thanks again!

yiyu
