Hello Fabio, The Node Health Status is something that would show up if you were using a Node Health script for your TTs. It is normal for it to be "N/A", otherwise (by default). Your TaskTrackers are functioning fine I'd believe -- try out a few jobs!
If you do wish to setup node health scripts, check out this documentation page on it: http://hadoop.apache.org/common/docs/current/cluster_setup.html#Monitoring+Health+of+TaskTracker+Nodes On Thu, Apr 28, 2011 at 7:49 PM, Fabio Souto <[email protected]> wrote: > Hi all, > > I installed and configured a 4 machine hadoop cluster.
