fiware-cosmos

I have a Hive client (written in Java) that worked just fine with the Global Instance of Cosmos at FIWARE Lab. However, it is not working anymore, it seems the client cannot connect (it times out). Has anything changed on the server-side? This is because the Global Instance of Cosmos at FIWARE Lab has been upgraded and now HiveServer2 is being run on the server side of Hive. Thus, everything in your code is still valid except for the following: Load org.apache.hive.jdbc.HiveDriver instead of org.apache.hadoop.hive.jdbc.HiveDriver . Change the JDBC connection schema from jdbc:hive to jdbc:hive2

When trying to persist an entity from Cygnus to Cosmos global instance it fails. Looking at the log file I see something like that: 2015 15:31:50,006 DEBUG [SinkRunner-PollingRunner-DefaultSinkProcessor] (org.apache.http.impl.conn.DefaultClientConnection.sendRequestHeader:273) - >> GET /webhdfs/v1/user/ms/def_serv/def_servpath/6_registervalues/6_registervalues.txt?op=getfilestatus&user.name=ms HTTP/1.1 12 Nov 2015 15:31:50,006 DEBUG [SinkRunner-PollingRunner-DefaultSinkProcessor] (org.apache.http.impl.conn.DefaultClientConnection.sendRequestHeader:276) - >> X-Auth-Token: xxxxxxxxxxxxxxxxxxx 12

I have deployed an Orion instance in FILAB and I have configured the Cygnus inyector in order to store information in Cosmos. But...let us imagine a scenario in which the number of entities increases drastically. In this hypothetical scenario one instance of Orion GE wouldn't be enough so it would be necessary to deploy more instances. What would be the scale procedure? Taking into account the maximum quotas are: VM Instances: 5 VCPUs: 10 Hard Disk: 100 GB Memory: 10240 MB Public IP: 1 I understand that quotas may be subject to changes but what would be the free account limit? What would be
