fiware-orion - Fiware - Cygnus 到 Cosmos，我无法上传数据到 HDFS

Question

我有一个带有 Cygnus 的 Orion 实例，订阅和通知工作正常，但我无法从我的实例向 cosmos.lab.fi-ware.org 发送文件。

我的 cygnus.conf :

# The next tree fields set the sources, sinks and channels used by Cygnus. You could use different names than the
# ones suggested below, but in that case make sure you keep coherence in properties names along the configuration file.

# one of them (this example shows how to configure 3 sinks at the same time).

一旦启用了从 Lanion 节点到西类牙节点的访问，则已修复。
