Subject [jira] Commented: (HBASE-23) UI listing regions should be sorted by address and show additional region state
Date Mon, 12 May 2008 21:33:55 GMT

stack commented on HBASE-23:
----------------------------

Yeah, I suppose showing offlined regions would be a bit tough unless you read the .META. 
Leave this one off the list.  Its possible to figure what you need using shell and only fellas
debugging will want the info (though if easy enough, you could print out whether a region
has 'references' -- this would demark the regions that still hold references to parent region).

On hostname, it is available?  If so, great.  I'd say replace the IP w/ hostname.  Thats what
most would prefer.

Regards load, there is ServerManager.getAverageLoad().  You could print this out in UI as
one of the cluster properties (load and average).  Otherwise, I there is the loadToServers
map which I think we're already reading.

Good stuff Jean-Daniel.

> Currently, looking at a cluster under load, you'll often trip over the disorientating
listing of more than one region with a null end key (Was seen by Billy yesterday and psaab
today).   UI should list out all of its attributes.
> Also sort region listings by server address so easier finding servers.
