【问题描述】:
我遇到了问题"Cygnus can not persist data on Cosmos global instance" 中讨论的相同类型的连接问题。但是,我读了之后没有找到解决办法。
现在,我最近在 FILAB 中部署了两个虚拟机(两个虚拟机都包含 Orion ContextBroker 0.26.1 和 Cygnus 0.11.0)。
当我尝试通过 Cygnus 在 Cosmos 上持久化数据时,我收到以下错误消息(两个 VM 中相同):
2015-12-17 19:03:00,221 (SinkRunner-PollingRunner-DefaultSinkProcessor)
[ERROR - com.telefonica.iot.cygnus.sinks.OrionSink.process(OrionSink.java:305)]
Persistence error (The /user/rmartinezcarreras/def_serv/def_serv_path/room1_room
directory could not be created in HDFS. Server response: 503 Service unavailable)
另一方面,当我尝试从任何 VM 的命令行发出请求时,我会得到下一个响应:
[root@orionlarge centos]# curl -v -X GET "http://cosmos.lab.fiware.org:14000/webhdfs/v1/user/rmartinezcarreras/?
op=liststatus&user.name=rmartinezcarreras" -H "X-Auth-Token: XXXXXXX"

不过,来自外部 VM(FILAB 外部):
[root@dsieBroker orion]# curl -v -X GET

op=liststatus&user.name=rmartinezcarreras" -H "X-Auth-Token: XXXXX"

还可以从我的 Cosmos 帐户中获得良好的结果。
我该如何解决这个问题?这似乎是一个连接问题。你能帮帮我吗?
提前谢谢你
【问题讨论】:
-
与您评论的其他问题一样,我将把球传给网络人员,因为这显然是一个连接问题。
-
网络人告诉我这应该修复。
-
我刚刚做了另一个测试,我仍然无法从 FILAB 连接到 Cosmos 全局实例。响应类似于上面的跟踪 2(...在最后从对等方接收数据时失败)。如果连接问题得到解决,什么可能导致 FILAB-COSMOS 出现这种通信问题?
-
FILAB 虚拟机出了点问题,因为在 FILAB 之外的机器上使用相同的 Cygnus 设置,我可以将数据保存在 Cosmos 中。
-
是的,我又把球传给了网络人。对不起:(
