Arun C Murthy updated HADOOP-4807:
----------------------------------
Status: Open (was: Patch Available)
Minor comments:
# I'd suggest we deprecate both the current ClusterStatus constructors and use
only the new one - this helps with the complication in write and readFields too.
# Rather than introduce {set|is}{Failed|Pending|Completed|Running|Killed}
methods in TaskInProgressStatus I'd suggest a single {get|set}Status which
takes/returns the enum which is called with appropriate values from
TaskInProgress.generateSingleReport.
# There are some debugging statements left over.
Long term: It would be really great to use the
TaskInProgressStatus.TaskInProgressStatusType to maintain the TIP's state
rather than all the booleans...
> 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.
