---------------------------------
Summary: Fold all the system tables to hbase:meta
Key: HBASE-22938
URL: https://issues.apache.org/jira/browse/HBASE-22938
Project: HBase
Issue Type: Brainstorming
Reporter: Duo Zhang
Quote my post on HBASE-15867 here, on how to deal with the dead lock when we
want to store replication queues to hbase:replication table.

We could add a special prefix in the row key for different system tables, and
make a special family for it. For example, for all the records in hbase:acl, we
could introduce a prefix like ':::acl:::', since we do not allow ':' in either
namespace or table name, so it will not conflict with the existing table
related records. And the family could be namd as 'acl'.
And we could make a special split policy that only splits at these special
prefixs, so it will not break any assumptions so far, as all the records for
the 'system table' are in the same region.

And I think there are also other advantages, for example the start up logic can
be greatly simplified.
