Subject [jira] [Commented] (HBASE-6594) Move tasks section above regions section in RegionServer UI
Date Thu, 16 Aug 2012 16:24:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6594?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13436071#comment-13436071

Andrew Purtell commented on HBASE-6594:
---------------------------------------

bq. Can the task list become long as well?
[~lhofhansl] Yes, it's not bounded. However, in practice the task list is short unless the
regionserver is sick. 
My thinking here is latency stats and top of the task list are most useful to ops at a glance
with frequent refresh. The region list gets in the way in that situation.

> With the new RegionServer UI, at the top of the page is the server metrics tab, then
the region list, then the task list, the software attributes. The region list could be lengthy,
so scrolling down to find the task list can take some time. Every refresh of the page resets
the view to [0,0]. Therefore "at a glance" information should come first, "above the fold",
 statistics at the top followed by the tasks section.
