Devaraj Das updated HADOOP-4807:
--------------------------------
Attachment: 4807.3.patch
Thanks Arun/Sharad for looking at this. I have incorporated the comments.
1) Made TaskInProgressStatusType a separate class all by itself and called it
TIPStatus
2) Factored TaskInProgressStatus functionality into TaskReport since that is
where it is needed
3) Added a new getClusterStatus method that takes a boolean argument and
depending on whether it is true, sets the task tracker names as well. If false,
only counts of blacklisted/active trackers are set (as is the behavior today).
I did this since I wanted to avoid iterations over the tasktracker list for
every call to assignTasks in CapacityScheduler, for example.
> Add framework hooks to get the running/completed/pending tasks for a given
> job. Add a way to query the list of currently active tasktrackers from the
> JobTracker.
