Question

我们使用提供的JAVA SDK将示例json事件推送到了Azure事件中心。然后我们创建了流分析作业，该作业从事件中心获取输入并将数据推送到Blob存储。但是我们已经观察到（从监视中）事件被推送到事件中心，但是我的流分析作业既未接收到事件也未引发任何异常（查看的活动日志）。我尝试了Internet上所有可用的故障排除解决方案，但仍然无法正常工作。

概述页面上的图形上没有显示输入事件

注意：我使用天蓝色的Twitter情绪分析尝试了上述流程（https://docs.microsoft.com/en-us/azure/stream-analytics/stream-analytics-introduction）并有效。

我们还为流分析工作启用了诊断日志，但是我们还没有发现任何东西。

事件肯定会被推送到事件中心，我们通过编写自己的事件中心使用者来对其进行测试。

已发布示例JSON事件：

{
  "timestamp":"2018-06-20T17:25:37.863Z",
  "name":"Alex",
  "city":"Aukland",
  "message":"Sample Logger"
}

事件中心发布者代码：

    ConnectionStringBuilder connStr = new ConnectionStringBuilder()
            .setNamespaceName("test-eventhub") 
            .setEventHubName("testEventhub")
            .setSasKeyName("testEventhub-access")
            .setSasKey("Endpoint=sb://test-eventhub.servicebus.windows.net/;"
                    + "SharedAccessKeyName=testEventhub-access;SharedAccessKey=xyz=");


    final Gson gson = new GsonBuilder().create();

    // The Executor handles all asynchronous tasks and this is passed to the EventHubClient instance.
    // The enables the user to segregate their thread pool based on the work load.
    // This pool can then be shared across multiple EventHubClient instances.
    // The following sample uses a single thread executor, as there is only one EventHubClient instance,
    // handling different flavors of ingestion to Event Hubs here.
    final ExecutorService executorService = Executors.newSingleThreadExecutor();

    // Each EventHubClient instance spins up a new TCP/SSL connection, which is expensive.
    // It is always a best practice to reuse these instances. The following sample shows this.
    final EventHubClient ehClient = EventHubClient.createSync(connStr.toString(), executorService);

    try {
        for (int i = 0; i < 10000; i++) {
            String payload = "{\"timestamp\":\"2018-06-20T17:25:37.863Z\",\"name\":\"Alex\",\"city\":\"Aukland\",\"message\":\"Sample Logger\"}";
            System.out.println(payload);
            //PayloadEvent payload = new PayloadEvent(i);
            byte[] payloadBytes = gson.toJson(payload).getBytes(Charset.defaultCharset());
            EventData sendEvent = EventData.create(payloadBytes);

            // Send - not tied to any partition
            // Event Hubs service will round-robin the events across all Event Hubs partitions.
            // This is the recommended & most reliable way to send to Event Hubs.
            ehClient.sendSync(sendEvent);
        }

        System.out.println(Instant.now() + ": Send Complete...");
       //System.in.read();
    } finally {
        ehClient.closeSync();
        executorService.shutdownNow();
    }
