如何在握手异常期间处理Bigquery Remote主机关闭连接

Question

在我的ExecutorService中，只要任务（包含要传输的数据）可用，执行程序就会激活一个线程以向Google Bigquery发送流请求。我发现一段时间后，它抛出异常：

我认为这是因为我没有刷新我的凭据。所以我更新了我的代码如下。但它没有帮助解决问题。我查看了谷歌API文档（https://developers.google.com/drive/web/credentials）。但它只为Web应用程序帐户提供了方法。但我使用的是Java应用程序的服务帐户。

或者我的问题根本不是由于凭证？我该如何解决？
