Solución a errores de publicación en Data Hub: Cómo resolver problemas de publicación y conexión en Data Hub

Hey there,

I'm trying to get familiar with Data Hub (following this page: https://help.hybris.com/6.3.0/hcd/8155bc6d95d4419793dcf54e0e9a5841.html). Everything before this works as expected, but when it comes to publish data, I always get an error:

2017-05-22 13:44:14,050 [INFO] [c.h.d.r.r.PoolActionResource] Received POST request /publications with args [GLOBAL,org.glassfish.jersey.server.internal.routing.UriRoutingContext@31033815,PublicationActionData{targetSystemPublications=[TargetSystemPublicationData{publicationId=null, startTime=null, endTime=null, status='null', targetSystemName='FileAdapterTargetSystem', actionId=null, poolName='null', canonicalItemCount=0, internalErrorCount=0, externalErrorCount=0, numberOfErrors=0, ignoredCount=0}]PoolActionData{actionId=null, type='PUBLICATION', startTime=null, endTime=null, status='null', poolName='GLOBAL'}}] 2017-05-22 13:44:14,077 [DEBUG] [c.h.d.s.i.DefaultEventPublicationService] Publishing data hub event : PerformPublicationEvent{actionId=1, systemUrl=' http://localhost:8080/datahub-webapp/v1', targetPublicationIds=[1]} 2017-05-22 13:44:14,110 [DEBUG] [c.h.d.p.i.DefaultProcessMonitor] Registered Publication #1: 1 processes running 2017-05-22 13:44:14,114 [DEBUG] [c.h.d.s.i.DefaultEventPublicationService] Publishing data hub event : PublicationStartedEvent{actionId=1} 2017-05-22 13:44:14,138 [DEBUG] [c.h.d.s.i.DefaultPublicationActionService] Pinging target system FileAdapterTargetSystem for target system publication id 1 and pool GLOBAL. 2017-05-22 13:44:14,220 [WARN] [c.h.d.p.TargetSystemAvailabilityRetryListener] The target system FileAdapterTargetSystem is unavailable for target system publication id 1 and pool GLOBAL: URI is not absolute .

I highlighted the errors in bold. Especially the second one confuses me... I've installed a complete blank Tomcat and Hybris with no additional extension or stuff like that. All I'm trying to do is execute this command:

curl -u admin:nimda --data-binary @datafile2 -H "Content-Type:application/json" --request POST http://localhost:8080/datahub-webapp/v1/pools/GLOBAL/publications

The content of datafile2 is as follows:

 {
       "poolName": "GLOBAL",
         "targetSystemPublications": [
             {
           "targetSystemName": "FileAdapterTargetSystem"
           }
         ]
 }

Does anybody have a clue what might be the issue and what I can do about that?

Update (May, 29th 2017, copied & pasted from my comment below): The solution for my problem is that it seems like there has to be another (additional) extension (which is not mentioned on the help pages) within the opt/datahub/extensions directory - at least if you want to run Data Hub locally as a testing environment. This extension could be (for example) datahub-file-adapter-target-6.0.0.0-RC
