> PhoenixAccessController checks permissions only at table level when creating

> Project: Phoenix

>
>
> The {{PhoenixAccessController#preCreateTable()}} method is invoked everytime
> a user wants to create a view on a base table. The {{requireAccess()}} method
> takes in tableName as the parameter and checks for user permissions only at
> that table level. The correct approach is to also check permissions at
> namespace level, since it is at a larger scope than per table level.
> For example, if the table name is {{TEST_SCHEMA.TEST_TABLE}}, it will created
> as {{TEST_SCHEMA:TEST_TABLE}} HBase table is namespace mapping is enabled.
> View creation on this table would fail if permissions are granted to just
> {{TEST_SCHEMA}} and not on {{TEST_TABLE}}. It works correctly if same
> permissions are granted at table level too.
