Instead of being an ephemeral state set by hbck, maintenance mode is now
an explicit toggle set by either configuration property or environment
variable. In maintenance mode, master will host system tables and not
assign any user-space tables to RSs. This gives operators the ability to
affect repairs to meta table with fewer moving parts.
With this change if hbase.wal.meta_provider is not explicitly set,
it uses whatever set with hbase.wal.provider. this change avoids a use
case of unexpectedly using two different providers when only
hbase.wal.provider is set to non-default but not hbase.wal.meta_provider.
This change also include document (architecture.adoc) update
Also, this is a port from master to branch-2
