【问题描述】：
我在运行大型 (>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：远程主机关闭 握手期间的连接
该错误不是致命的，但是，一旦开始，它大约每 30 秒重复一次。显示此错误的作业永远不会完成（我已经等待了超过预期运行时间的 4 倍）并且产生的结果非常有限（不到预期输出的 4%）。有限的产出，当生产出来时，在工作的早期就收到了，之后就不再生产了。
我同时使用 BigQueryIO 和 JdbcIO Apache 光束源和接收器。
请务必注意，我的工作在 6 月初正常工作，但从 7 月初开始出现此错误。
我在 Google 的企业支持部门有一个未决案例，但我们只能说结果尚未公布。谷歌产生的唯一兴趣点是可能会发生错误，“以防工人扩大规模并大量访问云存储”。
但是，该声明没有附加任何解决方案。 这是日志中记录的完整错误的示例：
