-------------------------------------
Hello,
This Question was answered at Nov 6 '17 in the ask.fiware.org portal with the following content:
Hello, I am checking your question and I notice that the error is related to the Phoenix driver. Currently, Cygnus has a native support to this Sinks: Cartodb, ckan, dynamo, hdfs, hive, mongodb, mysql, postgresql, but doesn't have the native driver for Phoenix, that is the reason why you receive the message that Cygnus doesn't found the driver for Phoenix. It means that you can't connect if you don't have the corresponding driver, some insights about how to add the Phoenix driver in Apache flume are posted in https://phoenix.apache.org/flume.html

> +Question:+
> Make Fiware-Cygnus storing to Apache-Phoenix database
> +Description:+
> I'm new to Cygnus and to Phoenix db. I want Cygnus to store data in an Apache Phoenix db, so I have to configure the Phoenix Sink to work with Cygnus.
> I know that Cygnus is an extension of Apache Flume, so any Flume agent can work with it by default (theoretically). I configured my Flume agent agent_phoenix.conf file for Cygnus like this:

> ----EDIT----
> I just made a step forward. I edited my flume-env.sh file inside cygnus/conf directory, and specified as FLUME_CLASSPATH the .jar file containing PhoenixSink java class. Now launching the same command that I wrote above it starts configuring (apparently well) then I get this error msg:

> -------------EDIT 2-------------------
> Ok I'm gettint closer, but this error has no sense. I solved the jdbc problem by copying the right phoenix JAR in classpath, then I got some dependecies errors and I solved them by copying other JARs in classpath. Now I get the same old error of jdbc. I really can't figure out what is happening:
