> +Question:+
> Cygnus dosen't forward the data to HDFS
> +Description:+
> After configuring Cygnus in my filab vm, I'm getting this error:
> [ERROR - es.tid.fiware.fiwareconnectors.cygnus.sinks.OrionSink.process(OrionSink.java:140‌​)] Persistence error (The default_org/XYZ directory could not be created in HDFS. HttpFS response: 400 Bad Request)
> A concrete example will this one:
> (SinkRunner-PollingRunner-DefaultSinkProcessor) [ERROR - es.tid.fiware.fiwareconnectors.cygnus.sinks.OrionSink.process(OrionSink.java:140)] Persistence error (The default_org/<XX:YY:ZZ:AA:BB>-<entity-type> directory could not be created in HDFS. HttpFS response: 400 Bad Request)
> I am following the next manual to run cygnus:
> https://github.com/telefonicaid/fiware-connectors/tree/develop/flume but the problem persist.
> My cygnus.conf is the next one:
> #=============================================
> # To be put in APACHE_FLUME_HOME/conf/cygnus.conf
> #
> # General configuration template explaining how to setup a sink of each of the available types (HDFS, CKAN, MySQL).
> #=============================================
> # The next tree fields set the sources, sinks and channels used by Cygnus. You could use different names than the
> # ones suggested below, but in that case make sure you keep coherence in properties names along the configuration file.
> # Regarding sinks, you can use multiple types at the same time; the only requirement is to provide a channel for each
> # one of them (this example shows how to configure 3 sink types at the same time). Even, you can define more than one
> # sink of the same type and sharing the channel in order to improve the performance (this is like having
> # multi-threading).
