Dmytro Molkov updated MAPREDUCE-892:
------------------------------------
Attachment: MAPRED-892.patch.3
Moved the extended ClusterStatus information to the ClusterStatus class instead
of creating a new class.
The command line tool is now called -list-trackers (in addition to
-list-active-trackers and -list-blacklisted-trackers)
The ClusterStatus also holds the information about where the tasks of the
current jobs were running when they finish. The TaskTrackerStatus object only
carries information about currently running tasks.
> 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)
