I am trying to persist my Orion data into the public cosmos.lab.fi-ware.org instance using Cygnus. Cygnus is up and running and the HDFSSink part of my /usr/cygnus/conf/agent_1.conf looks like this:

# OrionHDFSSink configuration cygnusagent.sinks.hdfs-sink.channel = hdfs-channel cygnusagent.sinks.hdfs-sink.type = com.telefonica.iot.cygnus.sinks.OrionHDFSSink cygnusagent.sinks.hdfs-sink.enable_grouping = false cygnusagent.sinks.hdfs-sink.backend_impl = rest cygnusagent.sinks.hdfs-sink.hdfs_host = cosmos.lab.fi-ware.org cygnusagent.sinks.hdfs-sink.hdfs_port = 14000 cygnusagent.sinks.hdfs-sink.hdfs_username = myUsernameInCosmosLabInstance cygnusagent.sinks.hdfs-sink.hdfs_password = myPasswordInCosmosLabInstance cygnusagent.sinks.hdfs-sink.oauth2_token = myTokenForCosmosLabInstance cygnusagent.sinks.hdfs-sink.hive = true cygnusagent.sinks.hdfs-sink.hive.server_version = 2 cygnusagent.sinks.hdfs-sink.hive.host = cosmos.lablfi-ware.org cygnusagent.sinks.hdfs-sink.hive.port = 10000 cygnusagent.sinks.hdfs-sink.hive.db_type = default-db

I add a new subscription with Cygnus as the reference endpoint and I send an update to previously created NGSIEntity, but nothing appears in my cosmos.lab.fi-ware.org instance. When looking at /var/log/cygnus/cygnus.log I cant find nothing useful, and I find some Java errors.

I am using Orion v. 0.28 and Cygnus v. 0.13.

正如日志所说：

Could not open connection to jdbc:hive2://cosmos.lablfi-ware.org:10000/default: java.net.UnknownHostException: cosmos.lablfi-ware.org

您必须配置正确的 Hive 端点：

cygnusagent.sinks.hdfs-sink.hive.host = cosmos.lab.fiware.org

代替：

cygnusagent.sinks.hdfs-sink.hive.host = cosmos.lablfi-ware.org

注意：您可能已经注意到我使用了cosmos.lab.fiware.org. 两者cosmos.lab.fiware.org和cosmos.lab.fi-ware.org都是有效的，第一个是首选。

要查找 Orion 保存在我的 Cosmos 全局实例中的数据：

  1. 来自Hadoop：

# hive hive> select * from myUsernameInCosmosLabInstance_def_serv_def_servpath_room1_room_column;

  1. 替代方法：

# hadoop fs -ls /user/myUsernameInCosmosInstance/def_serv/def_servpath/Room1_Room/Room1_Room.txt
