      Description

      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.

        Can the task list become long as well?

        Can the task list become long as well?

        Lars Hofhansl Yes, it's bounded but to IIRC 1000 entries. 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.
