> h1. Purpose
> In failover/fail-back scenarios, a Hive database needs to be read-only, while 
> other one is writable to keep a single source of truth.
> h1. User-Facing Changes
> Yes. EnforceReadOnlyDatabaseHook class implements ExecuteWithHookContext 
> interface. hive.exec.pre.hooks needs to have the class name to initiate an 
> instance. The "readonly" database property can be configured to turn it on 
> and off.
> h2. Allowed read operations
> All read operations without any data/metadata change are allowed.
>  * EXPLAIN
>  * USE(or SWITCHDATABASE)
>  * REPLDUMP
>  * REPLSTATUS
>  * EXPORT
>  * KILL_QUERY
>  * DESC prefix
>  * SHOW prefix
>  * QUERY with SELECT or EXPLAIN. INSERT, DELETE, UPDATE are disallowed.
> h2. Allowed write operations
> Most of write operations that change data/metadata are disallowed. There are 
> few allowed exceptions. The first one is alter database to make a database 
> writable. The second one is replication load to load a dumped database.
>  * ALTER DATABASE db_name SET DBPROPERTIES without "readonly"="true".
>  * REPLLOAD
> h1. Tests
>  * read_only_hook.q: USE, SHOW, DESC, DESCRIBE, EXPLAIN, SELECT
>  * read_only_delete.q
>  * read_only_insert.q
