AccessController has this:
```
@Override
public void preDisableTable(ObserverContext<MasterCoprocessorEnvironment>
c, TableName tableName)
throws IOException {
if (Bytes.equals(tableName.getName(),
PermissionStorage.ACL_GLOBAL_NAME)) {
// We have to unconditionally disallow disable of the ACL table when
we are installed,
// even if not enforcing authorizations. We are still allowing grants
and revocations,
// checking permissions and logging audit messages, etc. If the ACL
table is not
// available we will fail random actions all over the place.
throw new AccessDeniedException("Not allowed to disable " +
PermissionStorage.ACL_TABLE_NAME
+ " table with AccessController installed");
}
requirePermission(c, "disableTable",
tableName, null, null, Action.ADMIN, Action.CREATE);
}
```
Which is covered by
```
getMaster().getMasterCoprocessorHost().preDisableTable(tableName);
```
