> Regionserver groups needs to specially handle what it calls "special tables",
> tables upon which core or other modular functionality depends. They need to
> be excluded from normal rsgroup processing during bootstrap to avoid circular
> dependencies or errors due to insufficiently initialized state. I think we
> also want to ensure that such tables are always given a rsgroup assignment
> with nonzero servers. (IIRC another issue already raises that point, we can
> link it later.)
> Special tables include:
> * The system tables in the 'hbase:' namespace
> * The ACL table if the AccessController coprocessor is installed
> * The Labels table if the VisibilityController coprocessor is installed
> * The Quotas table if the FS quotas feature is active
> Either we need a facility where "special tables" can be registered, which
> should be in core. Or, we institute a blanket rule that core and all
> extensions that need a "special table" must put them into the 'hbase:'
> namespace, so the TableName#isSystemTable() test will return TRUE for all,
> and then rsgroups simply needs to test for that.
