use of org.apache.hadoop.hive.metastore.api.HiveObjectPrivilege in project hive by apache.

the class ObjectStore method listTableGrantsAll.

@Override

    boolean success = false;
    Query query = null;
    try {
        openTransaction();
        LOG.debug("Executing listTableGrantsAll");
        query = pm.newQuery(MTablePrivilege.class, "table.tableName == t1 && table.database.name == t2");
        query.declareParameters("java.lang.String t1, java.lang.String t2");
        List<MTablePrivilege> mSecurityTabPartList = (List<MTablePrivilege>) query.executeWithArray(tableName, dbName);
        LOG.debug("Done executing query for listTableGrantsAll");
        pm.retrieveAll(mSecurityTabPartList);
        List<HiveObjectPrivilege> result = convertTable(mSecurityTabPartList);
        success = commitTransaction();
        LOG.debug("Done retrieving all objects for listPrincipalAllTableGrants");
        return result;

Example 10 with HiveObjectPrivilege

use of org.apache.hadoop.hive.metastore.api.HiveObjectPrivilege in project hive by apache.

the class ObjectStore method convertPartition.

    List<HiveObjectPrivilege> result = new ArrayList<HiveObjectPrivilege>();
    for (MPartitionPrivilege priv : privs) {
        String pname = priv.getPrincipalName();
        PrincipalType ptype = PrincipalType.valueOf(priv.getPrincipalType());
        MPartition mpartition = priv.getPartition();
        MTable mtable = mpartition.getTable();
        MDatabase mdatabase = mtable.getDatabase();
        HiveObjectRef objectRef = new HiveObjectRef(HiveObjectType.PARTITION, mdatabase.getName(), mtable.getTableName(), mpartition.getValues(), null);
        PrivilegeGrantInfo grantor = new PrivilegeGrantInfo(priv.getPrivilege(), priv.getCreateTime(), priv.getGrantor(), PrincipalType.valueOf(priv.getGrantorType()), priv.getGrantOption());
        result.add(new HiveObjectPrivilege(objectRef, pname, ptype, grantor));
