I tested reliability of RegionServer crash, and found following problem:
Test:
(1) A table, inserted millions of rows. the I use hbase shell commant to
flush a memstores to disk, there are 25 regions.
(2) Kill a RS (no ROOT and META region), then scan the whole table, success.
(3) Kill another RS (with META region), then scan the whole table, fail.
Maybe meta and data mismatch.
(strangely there are 28 regions now, why? and following is the err log!)
