Hmm... AFAICT, if the regioninfo files is gone from a region directory (and I 
looked on hdfs, and it is gone), the region is hosed.

So I think it's time to rebuild the table. Sigh.

Any idea on why these disappeared? I was subjecting the system to a lot of load 
- an M/R task scanning a large table, and populating another table. There were 
some large cells crashing regionservers at a decent clip (trying to identify 
those large cells was part of the M/R task). So I was babysitting & restarting 
regionservers. 

After that, there were just some periodic writes over the weekend, but when I 
came back 4/10 regionservers had died. So a lot of random crashes going on..

Take care,
