Hi Carlos,
I did an example of connection between context broker and cosmos via Cygnus.
Here my config.
In cosmos.doc you can find my guide.

I hope that it will useful for you.

</div>dear carlos,

in fact, as an sme working in finodex you did correctly.
it will be your fiware coach (pasquale vitale in cc) that if not able to solve himself the issue, and i guess this time he will not, he will turn the ticket to the ge owner (francisco romero as indicated by juanjo).

ciao,
stefano

Hi Juanjo,

Thanks for you feedback, we sent it today because we wanted you to answer it tomorrow morning .

As you can see, a ticket has been created in Jira (https://jira.fiware.org/browse/HELC-1025). I used the fiware-finodex-coaching list, because we are a FINODEX project and they told us to do so. Should we create another ticket in the fiware-tech-help list also?

Best regards

Hi,

I copy Francisco (Paco) Romero who should be able to provide some help on this. I guess he won't be able to work on the matter until tomorrow since support is not granted out of office working hours.

Nevertheless, I believe that it is rather important that you open an issue so that a ticket on our help-desk system is created and then follow-up of support is feasible.

You may create a ticket in our helpdesk simply by sending an email to either fiware-lab-help (if it happens to be an issue which is mostly related to FIWARE Lab or the global COSMOS instance setup on the FIWARE Lab) or fiware-tech-help (if it happens to be an issue mostly related with the technology, i.e., with COSMOS in general and not the particular instance of COSMOS running on the FIWARE Lab).

Best regards,

– Juanjo

Hi everyone,

I'm Carlos Corrales, part of the development team at SAPIN (FINODEX012). We have been working hard in the application and now that it's finished and we are doing tests with final users, we are improving our code. A couple of months ago we were able to write data to our HDFS in the COSMOS Fiware machine (cosmos.lab.fi-ware.org) with our user (idelgado). As we are not using Cosmos for production right now (it will be used in the future), we left it aside. Now that we are checking that everything works as expected, we can see that our Cygnus connector is not able to write properly in HDFS. We haven't changed anything in the configuration, but we receive the following error when trying to write (flume.log file)

time=2015-09-13T15:11:36.744CEST | lvl=INFO | trans=1442149853-658-0000000000 | function=persist | comp=Cygnus | msg=es.tid.fiware.fiwareconnectors.cygnus.sinks.OrionHDFSSink[367] : [hdfs-sink] Persisting data at OrionHDFSSink. HDFS file (idelgado_SAPINnull), Data (

As you can see, the error is 401 Unauthorized. However, we can access the Cosmos machine using SSH, and the user/password in the cygnus.conf file. We also checked that the IP address of the Cosmos machine hasn't changed.

Could you please help us? We don't know what else to check...

Best regards
