Description

In our testing environment,
When master is initializing, we found conflict problems between master#assignAllUserRegions and EnableTable event, causing assigning region throw exception so that master abort itself.

We think we'd better refuse operations from Admin, such as CreateTable, EnableTable,etc, It could reduce error.
