public static void main(String[] args) {
        DateTime startTime = new DateTime(2016, 1, 1, 0,
                0, 0, DateTimeZone.UTC);
        DateTime endTime = new DateTime(2017, 1, 2, 0,
                0, 0, DateTimeZone.UTC);
        Interval interval = new Interval(startTime, endTime);
        PagingSpec pagingSpec = new PagingSpec(5, new HashMap<>());
        Granularity granularity = new SimpleGranularity(PredefinedGranularity.ALL);
        DruidSelectQuery query = DruidSelectQuery.builder()
                .dataSource("wikipedia")
                .descending(false)
                .granularity(granularity)
                .intervals(Collections.singletonList(interval))
                .pagingSpec(pagingSpec)
                .build();
        try {
            DruidConfiguration config = DruidConfiguration
                    .builder()
                    .host("localhost")
                    .port(8082)
                    .endpoint("druid/v2/")
                    .build();
            DruidClient client = new DruidJerseyClient(config);
            client.connect();
            String query1 = client.query(query);
            System.out.println(query1);
        } catch (Exception e) {
            e.printStackTrace();
