这是一个天鹅座代理日志：

我们保留与此问题相同的配置： Fiware Cygnus Error。
虽然Cygnus代理正确地从Context Broker Suscription接收数据，但Cosmos不会收到任何数据。
再次感谢，再次：）
答案 0 :(得分：0)
引起你对评论规则部分发表评论的原因（尽管如此，我认为这是因为我自己在<{3}} :)的错误的建议），该部分无法评论并且必须添加到配置中：
# Source interceptors, do not change
cygnusagent.sources.http-source.interceptors = ts gi
# TimestampInterceptor, do not change
cygnusagent.sources.http-source.interceptors.ts.type = timestamp
# GroupinInterceptor, do not change
cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
# Grouping rules for the GroupingInterceptor, put the right absolute path to the file if necessary
# See the doc/design/interceptors document for more details
cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf
一旦添加了该部分，很可能会出现另一个问题：Cygnus的表现将非常差（这就是我错误地建议用户https://jira.fiware.org/browse/HELC-986评论分组功能的原因，试图增加通过删除处理步骤的性能）。原因是最新版本的Cygnus（0.8.2）尚未准备好处理在Cosmos端运行的HiveServer2（该服务器最近从旧的HiveServer1升级到HiveServer2），并且每个持久性操作都会延迟很多。例如：

这将允许Cygnus继续，尽管没有自动创建Hive表，这是一个小问题（无论如何，由于当前与HiveServer2不兼容，它们将永远不会被创建）。当然，这将在Cygnus 0.9.0中修复（它将于2015年9月底发布）。
