> later edit: I've mixed up two issues here. The main problem is that a client
> (that could be HMaster) will read stale data from -ROOT- or .META. and not
> deal correctly with the raised exceptions.
> I've noticed this when the IP on my machine changed (it's even easier to
> detect when LZO doesn't work)
> Master loads .META. successfully and then starts assigning regions.
> However LZO doesn't work so HRegionServer can't open the regions.
> A client attempts to get data from a table so it reads the location from
> .META. but goes to a totally different server (the old value in .META.)
> This could happen without the LZO story too.
