Subject [jira] [Created] (PHOENIX-4528) PhoenixAccessController checks permissions only at table level when creating views

Karan Mehta created PHOENIX-4528:
------------------------------------

             Summary: PhoenixAccessController checks permissions only at table level when
creating views
                 Key: PHOENIX-4528
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4528
             Project: Phoenix
          Issue Type: Bug
            Reporter: Karan Mehta


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.
