Michael Bieniosek commented on HBASE-450:
-----------------------------------------
> currently you can see all the regions that a region server has open by
> viewing the region server gui on port 60030
That's true, but I have 40 regionservers, so it takes a long time to go through
them all.
I did manage to select * from .META., which gave me the region -> server
mapping.
> [gui] mapping from row name to hosting regionserver

> Occasionally something will go wrong with hbase. This is often due to an
> overloaded regionserver or datanode. For diagnostic purposes, it would be
> nice to have a gui way to figure out which regionserver a particular row
> lived on.
> It would be even nicer if I could also see which datanodes are hosting the
> data for the regionserver.
