Java Hbase API выдает RetriesExhaustedException при написании тестов JUnit

0 голосов
/ 08 января 2020

я пытаюсь написать JUnit для следующего метода, который отлично работает, когда я выполняю метод нормально, но при вызове модульных тестов он генерирует исключение RetriesExhaustedException в result.get () .

Метод для тестирования: 

    @Override
public Event findEvents(String id) throws IOException {
    Table eventsTable = null;
    Connection connection = null;
    Event event = null;
    boolean iFlag = false;
    boolean aFlag = false;
    boolean fFlag = false;
    try {
        connection = connectionPool.get();
        eventsTable = connection.getTable(TableName.valueOf(configuration.getEventsTable()));
        Get g = new Get(Bytes.toBytes(id.replaceAll(STRPATTERN, "")));
        Result r = eventsTable.get(g);// Exception occurs throwing RetiresExhaustedException
        if (!r.isEmpty()) { 
            event = genericRowRowMapperMapper.mapEventDetails(r, HbaseConstants.getEventheaderCf1(),
                    HbaseConstants.getEventbodyCf1(), iFlag, aFlag, fFlag);
            Util.replaceAid(event, id);
        }

    } finally {
        CGUtil.closeTable(eventsTable);
        releaseConnection(connection);
    }
    return event;
}

Метод тестирования: 

@Test(expected = Exception.class)
public void findEventsTest() throws Exception {

    String flexid = "25652365";
    Map<String, Event> eventMapF = new HashMap<>();
    Event eventF = new Event();
    Activity activityF = new Activity();
    activityF.setId("25652365");
    eventF.setActivity(activityF);
    eventMapF.put("25652365", eventF);

    Event evF = hBaseRepository.findEvents(flexid);
    assertNull(evF);
}

Я пытался изменить время ожидания увеличения c свойство из файла hbase-site. xml, но контрольный пример еще не пройден, исключение аналогично.
