Question

我的管道很简单。

Pipeline p = Pipeline.create();
         p.apply("Read", (BigtableIO.read().withBigtableOptions(BIGTABLE_OPTIONS)).withKeyRange(keyRange).withTableId("myTable"));
        p.run().waitUntilFinish();

但是当我跑步时，我经常收到：

我已经通过命令行在我的IDE里面试过了。

每次尝试我都会遇到这个错误。

我在Windows环境中运行。

任何帮助都将不胜感激。

感谢。

我认为这是Cloud Bigtable客户端中的问题，已在更高版本中修复。 Beam 2.1.0使用新版本，请尝试使用Beam 2.1.0并告知我们问题是否仍然存在。
