Filter HMS results

After you write an API to filter data from Hive, you need to know how to set up the API, enable it, and disable it. You need to add few Hive metastore (HMS) properties hive-site.xml using the Cloudera Manager Safety Valve.

HMS can perform server-side filtering of data returned by a read operation. Filtering is enabled by default, which shows the results of statements, such as SHOW TABLES or SHOW DATABASES, based on who the user is. You can disable filtering by setting a boolean flag and hook. The hook identifies the class name that implements the filtering. You add the following properties and values in hive-site.xml for HMS API-Ranger integration:
Value: true (to do filtering) or false (no filtering)

Add properties as described in the previous section.
