      Description

      I dropped a table with 121 regions, ans read from the web UI. Afterwards, most of the regions went away, but 6 remained counted and listed in the web UI. select * from .META. shows no rows, so in reality the regions are gone. This inconsistency gives a poor sense of the consistency of HBase.

        I'm not seeing any problem in the UI. I created a table with 7 regions (granted, not exactly 121 regions), and after I dropped it all those regions disappeared from the UI immediately. I would think that, especially since this issue was reported so long ago, it's probably become a non-issue. Although it's hard to say exactly how the UI would scale with 121 regions.
