> We need a way for job schedulers such as HADOOP-3445 and HADOOP-3476 to provide info
to display on the JobTracker web interface and in the CLI. The main things needed seem to
be:
> * A way for schedulers to provide info to show in a column on the web UI and in the CLI
- something as simple as a single string, or a map<string, int> for multiple parameters.
> * Some sorting order for jobs - maybe a method to sort a list of jobs.
> Let's figure out what the best way to do this is and implement it in the existing schedulers.
> My first-order proposal at an API: Augment the TaskScheduler with
> * public Map<String, String> getSchedulingInfo(JobInProgress job) -- returns key-value
pairs which are displayed in columns on the web UI or the CLI for the list of jobs.
> * public Map<String, String> getSchedulingInfo(String queue) -- returns key-value
pairs which are displayed in columns on the web UI or the CLI for the list of queues.
> * public Comparator<JobInProgress> getJobComparator() -- returns a comparator that
can be used to determine the order in which jobs will be run, for sorting the jobs in the
CLI.
> * public List<String> getQueues();
