Dmytro Molkov updated MAPREDUCE-892:
------------------------------------
Attachment: 0001-First-iteration-of-adding-the-task-tracker-reporting.patch
This patch adds a new command line argument to the JobClient:
-list-trackers-info
It is an improvement of -list-active-trackers/-list-blacklisted-trackers that
actually prints out information about a number of tasks currently running on
the tracker, tasks progress, maximum task capacity, etc.
Also added a jsp page that returns all the same info in JSON format
> command line tool to list all tasktrackers and their status

> The "hadoop mradmin -report" could list all the tasktrackers that the
> JobTracker knows about. It will also list a brief status summary for each of
> the TaskTracker. (This is similar to the hadop dfsadmin -report command that
> lists all Datanodes)
