Subject [jira] Commented: (HBASE-23) UI listing regions should be sorted by address and show additional region state
Date Mon, 12 May 2008 22:27:55 GMT

Yeah, I suppose showing offlined regions would be a bit tough unless you read the .META. Leave
this one off the list

Funny how there is a onlineRegions attribute in HRegionServer but no offlineRegions. At first
glance it seems logic that the two exists but it isn't. Bit misleading.

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

Yeah in ISA. This is the same as in the dfshealth.jsp page in hadoop ui. I added a getHostname
method in HServerAddress just like getPort or getBindAddress to get it in master.jsp

Regards load, there is ServerManager.getAverageLoad(). You could print this out in UI as one
of the cluster properties (load and average).
{quote}

Ok.

{quote}
Otherwise, I there is the loadToServers map which I think we're already reading.
{quote}

Indeed, this is why I was wondering why that average load by server was nowhere to be found.

> 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.
