Get statement enhancements Added support and privilege checks for the following commands:
get functions for library get procedures for library get table_mapping functions for library
get indexes on table get objects on table get views on table get views on view
get libraries in schema get objects in view get tables in view get views in view
get indexes for user get tables for user get libraries for user get views for user
Changed "get libraries for schema" to include libraries where the current user has execute privilege on one of the libraries routines (functions, procedures, or table_mapping functions).
Addressed a performance issue when determining if the user has column level privileges. If the user has granted privileges against native Hive tables through EsgynDB, we need to get the column name from Hive. The call to get the column, by calling hivemd, is very expensive. This change checks to see if the requested user has been granted any column level privileges on a hive table. If so, we will go ahead and do the mapping (call hivemd). If not, then we will not include the hivemd fragment for the query. Since we are scanning the column privileges table anyway, we also see if the requested user (or their roles) has been granted any privileges. If so, we include the column privileges check in the query.
Commented out get statements that we do not support at this time.
