Subject [jira] [Resolved] (MAPREDUCE-536) The information displayed by the capacity scheduler can be improved
Date Mon, 21 Jul 2014 17:02:42 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-536?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Allen Wittenauer resolved MAPREDUCE-536.

    Resolution: Incomplete

Closing this as stale given the UI is completely different now.

>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-536
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>            Reporter: Amar Kamat
> As of now the information displayed by the capacity scheduler is sequential. Following
are some ways I think we can improve the display
> - It would make more sense if we display it as a table where comparing the information
across queues would be easy. Something like
> || ||Queue1||Queue2||
> |guaranteed cap|75%|25%|
> - Along with  {{Reclaim Time Limit}} there should be a hint/info about how much time
capacity-scheduler thinks it will take to reclaim i.e it would be nice to know the time left
to reclaim.
> || ||Queue1||Queue2||
> |Reclaim time limit|300000|300000|
> |Time left to reclaim|500|120000|
> - All the timing information should have units specified. {{Reclaim time limit : 300000}}
doesnt give any information what the unit is.
> || ||Queue1||Queue2||
> |Reclaim time limit|5 mins|5 mins|
> |Time left to reclaim|500 msec| 2 mins|
> - Common information like disclaimers can move out of the table/display to a common place.
> - Showing guaranteed and (actual) running tasks doesnt convey much info. It should be
shown together. Something like 
> || ||Queue1||Queue2||
> |running/guaranteed maps|1/16|15/16|
> - We can also improve/enhance the way boolean information is displayed using ticks and
crosses. Something like
> || ||Queue1||Queue2||
> |Priorities|(/)|(x)|
