Hemanth Yamijala commented on HADOOP-3930:
------------------------------------------
We probably also need a way to get all the configured queues. Something like:
- public List<String> getQueues();
By default, this would return the single default queue that is there today in
the jobtracker. Makes sense ?
> Decide how to integrate scheduler info into CLI and job tracker web page

> 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.
