.META. can only have one Region after 0.96?

hi, there.

I have noticed that https://issues.apache.org/jira/browse/HBASE-3171 has
dropped the -ROOT- Region, and use .META. Region only.
If I can remember the previous logic of hbase, it can support .META. table
splitting when necessary,
from the new patch, it seems to me that it can only support  only one
region existing in .META.



Any comments is appreciated, Thanks.

Thanks for Matteo's quick reply. Maybe I have missed so many jira of hbase.

The .META. table was marked as not splittable in 0.20, see HBASE-2415 for
more details
