Michael Stack commented on HBASE-23103:
---------------------------------------
Or, if querying meta table state, MetaTableAccessor goes to ask the Master
rather than ZK; then I could keep state transient such that if Master dies, we
default back to enabled for hbase:meta. That might be better. Could also make
it so Admin functions all go to Master for table state and only
AsyncRpcRetryingCaller (and thrift) uses this new MTA exclusively. Something
like that.

> Task that comes of parent issue. Parent makes it so we go via Master to
> figure state of a table. It is the authority and since the parent issues adds
> being able to enable/disable hbase:meta, table state is now in two places --
> in hbase:meta table... and elsewhere for the hbase:meta's state. Rather than
> have client go to two locations dependent on which table is being asked
> about, parent made it so we went to master. Parent allows that this puts more
> load on the Master. [~zhangduo] brings up the valid concern that it might be
> too much or that dependent on the Master for state puts Master too much
> in-line with read/writes.
> This issue is a survey to figure how much load and how much state-in-master
> could mess up inline read/writes.
