Example 6 with MRole

use of org.apache.hadoop.hive.metastore.model.MRole in project hive by apache.

the class ObjectStore method listMRoles.

public List<MRoleMap> listMRoles(String principalName, PrincipalType principalType) {
    boolean success = false;
    Query query = null;
    List<MRoleMap> mRoleMember = new ArrayList<>();
    try {
        LOG.debug("Executing listRoles");
        openTransaction();
        query = pm.newQuery(MRoleMap.class, "principalName == t1 && principalType == t2");
        query.declareParameters("java.lang.String t1, java.lang.String t2");
        query.setUnique(false);
        List<MRoleMap> mRoles = (List<MRoleMap>) query.executeWithArray(principalName, principalType.toString());
        pm.retrieveAll(mRoles);
        success = commitTransaction();
        mRoleMember.addAll(mRoles);
        LOG.debug("Done retrieving all objects for listRoles");
    } finally {
        rollbackAndCleanup(success, query);
    }
    if (principalType == PrincipalType.USER) {
        // All users belong to public role implicitly, add that role
        // TODO MS-SPLIT Change this back to HMSHandler.PUBLIC once HiveMetaStore has moved to
        // stand-alone metastore.
        // MRole publicRole = new MRole(HMSHandler.PUBLIC, 0, HMSHandler.PUBLIC);
        MRole publicRole = new MRole("public", 0, "public");
        mRoleMember.add(new MRoleMap(principalName, principalType.toString(), publicRole, 0, null, null, false));
    }
    return mRoleMember;
}
