Subject Re: how to connect to remote hadoop dfs by eclipse plugin?
Date Thu, 14 May 2009 08:06:45 GMT
Why don't you use it with localhost? Does it have a disadvantage?
As far as I know, there were several host <=> IP problems in hadoop, but
that was a while ago, I think these should have been solved..

It's can also be about the order of IP conversions in IP table file.
