Subject [jira] [Commented] (MAPREDUCE-3328) mapred queue -list output inconsistent and missing child queues

Ravi Prakash commented on MAPREDUCE-3328:
-----------------------------------------

I am wondering what is the best way to display the list of queues. I am leaning towards an
output like this (I'll fix the capacity numbers after this)

======================
Queue Name : default
Queue State : running
Scheduling Info : queueName: "default", capacity: 0.7, maximumCapacity: 90.0, currentCapacity:
0.0, state: Q_RUNNING,
======================
Queue Name : test
Queue State : running
Scheduling Info : queueName: "test", capacity: 0.2, maximumCapacity: -1.0, currentCapacity:
0.0, state: Q_RUNNING,
    ======================
    Queue Name : a1
    Queue State : running
    Scheduling Info : queueName: "a1", capacity: 0.2, maximumCapacity: -1.0, currentCapacity:
0.0, state: Q_RUNNING,
    ======================
    Queue Name : a2
    Queue State : running
    Scheduling Info : queueName: "a2", capacity: 0.2, maximumCapacity: -1.0, currentCapacity:
0.0, state: Q_RUNNING,
======================
Queue Name : test2
Queue State : running
Scheduling Info : queueName: "test2", capacity: 0.1, maximumCapacity: 5.0, currentCapacity:
0.0, state: Q_RUNNING,
    ======================
    Queue Name : a3
    Queue State : running
    Scheduling Info : queueName: "a3", capacity: 0.2, maximumCapacity: -1.0, currentCapacity:
0.0, state: Q_RUNNING,
    ======================
    Queue Name : a4
    Queue State : running
    Scheduling Info : queueName: "a4", capacity: 0.2, maximumCapacity: -1.0, currentCapacity:
0.0, state: Q_RUNNING,

What do you think?

>          Issue Type: Bug
>          Components: mrv2
>    Affects Versions: 0.23.0

> When running mapred queue -list on a 0.23.0 cluster with capacity scheduler configured
with child queues.  In my case I have queues default, test1, and test2.  test1 has subqueues
of a1, a2.  test2 has subqueues of a3 and a4.
> - the child queues do not show up
> - The output of maximum capacity doesn't match the format of the current capacity and
capacity.  the latter two use float while the maximum is specified as int:
> Queue Name : default 
> Queue State : running 
> Scheduling Info : queueName: "default", capacity: 0.7, maximumCapacity: 90.0, currentCapacity:
0.0, state: Q_RUNNING,  
> ======================
> Queue Name : test 
> Queue State : running 
> Scheduling Info : queueName: "test", capacity: 0.2, maximumCapacity: -1.0, currentCapacity:
0.0, state: Q_RUNNING,  
> ======================
> Queue Name : test2 
> Queue State : running 
> Scheduling Info : queueName: "test2", capacity: 0.1, maximumCapacity: 5.0, currentCapacity:
0.0, state: Q_RUNNING,  
> ======================
> here default is configured to have capacity=70% and maximum capacity = 90%
