Sun Xin updated HBASE-24760:
----------------------------
Description:
In HBASE-22738 we allow tables fallback to specific rs groups, If there is no
online servers in the table's rsgroup.
-But for system tables, if there is no specified fallback rsgroup or the
servers in the fallback rsgroup all went down, It is necessary to allow system
tables fallback to any rsgroup in order to keey available at all times.-
For Availability, refactor design of rsgroup fallback, finally only introduced
one config property `hbase.rsgroup.fallback.enable`, allow all table, whether
or not system tables, fallback to the default rsgroup first, then fallback to
any group if no online servers in default rsgroup.
