             Summary: Create unit test for COUNT DISTINCT using compression
                 Key: PHOENIX-1462
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1462
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor
            Assignee: ramkrishna.s.vasudevan


Create a unit test for PHOENIX-1455 and ensure that it is calling the code to 
do compression. Something like this:
{code}
@Category(NeedsOwnMiniClusterTest.class)
public class CountDistinctCompressionIT extends 
BaseOwnClusterHBaseManagedTimeIT {
        
    @BeforeClass
    public static void doSetup() throws Exception {
        Map<String,String> props = Maps.newHashMapWithExpectedSize(3);
        // Must update config before starting server
          props.put(QueryServices.DISTINCT_VALUE_COMPRESS_THRESHOLD_ATTRIB, 
Long.toString(1));
        setUpTestDriver(new ReadOnlyProps(props.entrySet().iterator()));
    }

    @Test
    public void testDistinctCountOnColumn() throws Exception {
        String tenantId = getOrganizationId();
        initATableValues(tenantId, null, getDefaultSplits(tenantId), null);

        String query = "SELECT count(DISTINCT A_STRING) FROM aTable";

        Properties props = PropertiesUtil.deepCopy(TEST_PROPERTIES);
        Connection conn = DriverManager.getConnection(getUrl(), props);
        try {
            PreparedStatement statement = conn.prepareStatement(query);
            ResultSet rs = statement.executeQuery();
            assertTrue(rs.next());
            assertEquals(3, rs.getLong(1));
            assertFalse(rs.next());
        } finally {
            conn.close();
        }
    }
{code}
