Question

（在堆栈溢出时提交一个有趣的问答线程，可能对其他Snowflake用户有价值）

在我的项目中，我们正在从Azure blob通过Informatica云加载到Snowflake。

Informatica端的测试连接成功，我可以获取表，但是数据没有加载到表中。

Q：可以请一个人在这里指导吗？

Answer 1

A：看起来请求响应为NULL。您可以咨询内部网络团队是否配置了代理服务器，或者是否存在阻止通讯的内容？

Q：代理授权已被绕过，但错误仍然相同。

到达SDK插件后

MAPPING> SDKS_38029 [2019-09-04 11：06：39.981]加载的插件449900：[插件描述]。

MAPPING> SDKS_38024 [2019-09-04 11：06：39.998]插件449900初始化完成。

MAPPING> SDKS_38017 [2019-09-04 11：06：39.998] Writer SDK插件初始化完成。

工作在那儿停留了10分钟，没有采取任何进一步的行动。

作业因以下错误而终止。

[错误] com.informatica.powercenter.sdk.SDKException：com.informatica.cloud.adapter.cci.runtime.CCIGroupOperation.init（CCIGroupOperation。com.informatica.cloud.api.adapter.runtime.exception.InitializationException java：120）（位于com.informatica.cloud.api.adapter.writer.runtime.GenericWriterTargetDriver.initGroupOperation（未知源），位于com.informatica.cloud.api.adapter.writer.runtime.GenericWriterTargetDriver.init（未知源）

A：由于超时，我仍然听起来像是网络，代理或防火墙问题。您的内部网络团队应该能够跟踪流量，以协助阻止通信。也许某些网址需要列入白名单？我还在Informatica论坛上注意到了类似的错误。可能有助于查看他们的一些潜在解决方案（下面的链接）？
