Accumulo扫描/写入未在AWS EC2主机中使用Cloudera CDH 5.8.2的独立Java主程序中运行

我们试图在独立Java主程序Maven shade可执行文件中从Accumulo客户端jar 1.5.0运行simple write/sacn，如下所述，在AWS EC2 master中使用Putty

    public class AccumuloQueryApp {

      private static final Logger logger = LoggerFactory.getLogger(AccumuloQueryApp.class);

      public static final String INSTANCE = "accumulo"; // miniInstance
      public static final String ZOOKEEPERS = "ip-x-x-x-100:2181"; //localhost:28076

      private static Connector conn;

      static {
        // Accumulo
        Instance instance = new ZooKeeperInstance(INSTANCE, ZOOKEEPERS);
        try {
          conn = instance.getConnector("root", new PasswordToken("xxx"));
        } catch (Exception e) {
          logger.error("Connection", e);
        }
      }

      public static void main(String[] args) throws TableNotFoundException, AccumuloException, AccumuloSecurityException, TableExistsException {
        System.out.println("connection with : " + conn.whoami());

        BatchWriter writer = conn.createBatchWriter("test", ofBatchWriter());

        for (int i = 0; i < 10; i++) {
          Mutation m1 = new Mutation(String.valueOf(i));
          m1.put("personal_info", "first_name", String.valueOf(i));
          m1.put("personal_info", "last_name", String.valueOf(i));
          m1.put("personal_info", "phone", "983065281" + i % 2);
          m1.put("personal_info", "email", String.valueOf(i));
          m1.put("personal_info", "date_of_birth", String.valueOf(i));
          m1.put("department_info", "id", String.valueOf(i));
          m1.put("department_info", "short_name", String.valueOf(i));
          m1.put("department_info", "full_name", String.valueOf(i));
          m1.put("organization_info", "id", String.valueOf(i));
          m1.put("organization_info", "short_name", String.valueOf(i));
          m1.put("organization_info", "full_name", String.valueOf(i));

          writer.addMutation(m1);
        }
        writer.close();

        System.out.println("Writing complete ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`");

        Scanner scanner = conn.createScanner("test", new Authorizations());
        System.out.println("Step 1 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`");
        scanner.setRange(new Range("3", "7"));
        System.out.println("Step 2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`");
        scanner.forEach(e -> System.out.println("Key: " + e.getKey() + ", Value: " + e.getValue()));
        System.out.println("Step 3 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`");
        scanner.close();
      }

      public static BatchWriterConfig ofBatchWriter() {
        //Batch Writer Properties
        final int MAX_LATENCY  = 1;
        final int MAX_MEMORY = 10000000;
        final int MAX_WRITE_THREADS = 10;
        final int TIMEOUT = 10;

        BatchWriterConfig config = new BatchWriterConfig();   
        config.setMaxLatency(MAX_LATENCY, TimeUnit.MINUTES);
        config.setMaxMemory(MAX_MEMORY);
        config.setMaxWriteThreads(MAX_WRITE_THREADS);
        config.setTimeout(TIMEOUT, TimeUnit.MINUTES);

        return config;
      }
    }

当我们运行相同的代码写入Accumulo并从Accumulo内部读取Spark作业并提交给YANK集群时，它运行得非常完美。我们正在努力弄清楚这一点，但没有得到任何线索。请参阅下面描述的环境

AWS环境上的Cloudera CDH 5.8.2将4个EC2实例作为一个主实例和3个子实例

考虑一下私有IP就像

Hrm，这很奇怪，它是以Spark on Thread运行的，但作为一个常规Java应用程序。通常情况下，情况正好相反：

我将验证独立java应用程序的类路径上的JAR是否与Spark on Thread作业以及Accumulo服务器类路径使用的JAR匹配

如果这没有帮助，试着增加log4j级别以进行调试或跟踪，看看是否有什么事情发生在您身上。如果您很难理解日志所说的内容，请随时向发送电子邮件user@accumulo.apache.org你肯定会更加关注这个问题。

谢谢你的提示！当我将胖罐子放在Accumulo文档中提到的特定文件夹中时，我就能够运行它：

[impl.ThriftScanner] DEBUG: Error getting transport to ip-x-x-x-100:10011 : NotServingTabletException(extent:TKeyExtent(table:21 30, endRow:21 30 3C, prevEndRow:null))
