GCP数据流-SSLHandshakeException

Question

在运行大型（> 1000 cpus）和中型（100-1000 cpus）数据流作业时遇到以下问题：

异常：“ javax.net.ssl.SSLHandshakeException：握手期间远程主机关闭了连接

该错误不是致命的，但是一旦开始，它大约每30秒重现一次。 显示此错误的作业永远不会完成（我已经等待了预期运行时间的4倍以上），并且产生的结果非常有限（不到预期输出的4％）。 产量有限时，会在工作开始时收到，之后不再生产。

我同时使用BigQueryIO和JdbcIO Apache梁源和接收器。

重要的是要注意，我的工作在6月初可以正常工作，但是自7月初以来已经开始显示此错误。

我在Google的企业支持中有一个公开的案例，但是只能说结果不理想。 Google唯一感兴趣的一点是，“如果工作人员扩大规模并大量访问Cloud Storage，则可能会发生错误”。

但是，该语句没有附加解决方案。 这是记录在日志中的完整错误的示例：

在联机查看此问题的其他实例之后，该错误似乎仅在使用Java 7时发生。这是您的Java版本吗？

如果是，我建议尝试Java 8，看看是否可以解决该问题。 让我知道我们能否进一步提供帮助！
