Hi, Back to older release of Hadoop, the web admin page is able to show me the number of failed task for each node, so I can have a clue that a certain node with higher number is not healthy, disk issue for example. But after I upgrade to 2.2.0 release, I do not find any equivalent page, so my question is what's the replacement for this? I think it's critical from administration perspective.
