Arun Suresh commented on SENTRY-209:
------------------------------------
It looks like this is an issue with the Database Schema.
For some reason, DataNuclues does not update the 'SENTRY_ROLE_DB_PRIVILEGE_MAP'
Join table when granting Privileges.
On further investigation, I realized that if we remove the Primary Key (this is
actually not required in a Join table) and if we modify the package.jdo to
properly specify the m:n join.. things start to work again
> Empty list returned when calling listPrivilegesByRoleName

> Issue Type: Bug

> I tested this on a Mysql backend store.. I assume it would be the case for
> Postgres and Oracle too.. if the initSchema is called (and Datanucleus auto
> create is false)
> Steps to recreate (Using the thrift RPC client):
> 1) Create role :
> sentryClient.createRole(granter, granterGroups, adminRole);
> 2) Grant table privilege for role (I grant ALL on 100 tables) :
> sentryClient.grantTablePrivilege(granter, granterGroups, adminRole, server,
> db, "ALL");
> 3) List all privileges for role :
> Set<TSentryPrivilege> listPrivilegesByRoleName =
> sentryClient.listPrivilegesByRoleName(granter, granterGroups, adminRole);
> This returns an empty Set.
