Subject Re: Tasktracker status

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

with the tasktrackers... when I go to http://my-host:50030/machines.jsp?type=active in the
list of task trackers the "Node health status" of all task trackers appears as "N/A" and "Seconds
since node last healthy" is set to 0.
