stack commented on HBASE-1457:
------------------------------
This last patch seems to work great but the only odd thing is that it always
reassigns -ROOT- and .META. I flush -ROOT- region then I kill -9 the -ROOT-
server. I see the logs being split and then -ROOT- assigned. I see the
regionserver opening -ROOT- AND applying edits but then when -ROOT- scanner
runs, it says server and startcode are empty and things .META. assignment
invalid.
I'm looking into the above some.
