Hemanth Yamijala commented on HADOOP-3930:
------------------------------------------
bq. Left jobsToComplete as is.
I was thinking of something like:
{code}
private JobStatus[] getJobStatus(Collection<JobInProgress> jips, boolean
onlyRunning) {
// ..
if (onlyRunning) {
// consider only jobs which are running or prep.
}
}
{code}
Would that work ?
Regarding tests, taking cue from APIs like {{getAllJobs}}, I think it is OK to
provide wrapper APIs around the queue info related methods. These could be
package private and the test case can directly access these. So, something like:
{code}
JobQueueInfo[] getJobQueueInfos() { return jobSubmitClient.getJobQueueInfos(); }
private void displayQueueList() {
JobQueueInfo[] queues = getJobQueueInfos();
//
}
{code}
Agree with rest of your explanations.

> 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 Collection<JobInProgress> getJobs(String queueName) -- returns the
> list of jobs in a given queue, sorted by a scheduler-specific order (the
> order it wants to run them in / schedule the next task in / etc).
> * public List<String> getQueues();
