Subject [jira] [Updated] (MAPREDUCE-3816) capacity scheduler web ui bar graphs for used capacity wrong
Date Mon, 06 Feb 2012 15:21:59 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3816?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thomas Graves updated MAPREDUCE-3816:
-------------------------------------

    Attachment: capacityschedulerusedcap.png

In this screen shots, this is single node cluster 8 GB total memory. The default queue capacity
is 20% which would be 1638MB allocated to it.  You will see that its currently using 2G so
the usage is 125% - which is the utilization.

>          Components: mrv2
>    Affects Versions: 0.23.0

> The capacity scheduler web ui has bar graphs showing the capacity/used capacity/max capacity
for each queue. The used capacity it is showing is actually the % of its parents queue it
is using, which doesn't make sense on the bar graphs when compared to the capacity and max
capacity of that particular queue.  The bar graphs should be using utilization so that the
user can see that its using x% or the y% allocated to that queue.
> I will attach some screen shots showing the issue.
