Subject about .META. table's support for more than one region
Date Mon, 19 Sep 2011 05:23:09 GMT
It seems there are some assumptions in the code that .META. table only has one region FIRST_META_REGIONINFO
in the following areas:

1) .META. table update with user region info.
2) .META. regions assignment.
3) .META. table split handling.

HBase architecture allows for more than one region in .META. table. I wonder if such assumption
in the code is just due to the fact that hbase currently doesn't don't support large number
of regions yet; or there are other reasons behind it.

Thanks.

Ming
