Duo Zhang commented on HBASE-27355:
-----------------------------------
Usually, clients do not need to access system tables other than hbase:meta. On
branch-2.x, I'm not sure whether clients need to access hbase:namespace, but
theoretically they should get the namespace information from HMaster.
So I do not think it is a big deal for now, we can only deal with hbase:meta at
this time.
Thanks [~frostruan].

> If we have a large number of store files in a single region or the response
> from hdfs is slow, the region transition can be slow, the client may put a
> lot of pressure on the meta server when retrying. This may block the master
> system read requests. Maybe we can set a special priority for the master
> request to isolate read requests from master and client.
