Yes of course, it sounds good!
I'll create a different thread for questions that may arise!
Thank you,

Hello Michalis,
Welcome back! :)
Yes, indeed, the issue got solved.
I would propose you write the missing tests for the Apache Flink platform. Here
below the steps to follow (which are the two issues I will create right now):
(1) Re-run our benchmark jobs to make sure they are all working and improve the
readme file for how to run the benchmarks. This issue will put you into context
to solve the second issue below.
(2) Write the missing tests for Flink. Currently, we already have tests for
some operators of Flink but not all operators are covered. Therefore, we need
to write those missing tests, for which you can follow their counterparts in
the Spark platform.
Would that sound good for you?
Best,
Jorge

Hello!
I've been away for a few days for vacation and thus I've been inactive. I'm
actually really stuck with the whole task, I have not been able to run any
benchmark tests. I have tried troubleshooting and debugging without any success.
Running
$ wayang-submit org.apache.wayang.apps.wordcount.Main java
file://$(pwd)/README.md
in the "incubator-wayang/" directory,
after building it with maven, outputs
"Error: Could not find or load main class org.apache.wayang.apps.wordcount.Main
Caused by: java.lang.ClassNotFoundException:
org.apache.wayang.apps.wordcount.Main"
Running
$ java -cp target/classes org.apache.wayang.apps.wordcount.Main java
file://$(pwd)/README.md
in the "apache-wayang-0.6.0-incubating/wayang-benchmark/wayang-benchmark_2.12/"
directory,
after downloading the file from the downloads page OR after building it with
maven, outputs
"Error: Unable to initialize main class org.apache.wayang.apps.wordcount.Main
Caused by: java.lang.NoClassDefFoundError: org/apache/wayang/core/plugin/Plugin"
I also stumbled upon Biao's solution here
[https://github.com/bgeng777/incubator-wayang/blob/wordcount_fix/Tutorial.md]
and only then was I indeed able to run the word count example.
I don't know how to proceed from here! Any feedback or help would be
appreciated!
Thank you,
Michalis Vargiamis

I just commented on the issue with a bit more concrete problems that I noticed
the last days. Please let us know if you have any doubts.

Hello Michalis,
We are happy you found our project interesting. We are always welcoming new
hands to help moving Wayang forward. So, welcome to the Wayang community.
As I can understand you are just starting to get familiarised with Wayang, so
what about starting with step 0 and help us improving our Readme for installing
Wayang?
Currently, Wayang is not easy to get installed and we are facing a couple of
issues to have Wayang working because of some last changes.
@Zoi and @Alex (or anyone else :p) could you please recall us what are these
issues exactly?
At the same time, you could also help us rewriting our Readme file for the
installing Wayang and running the benchmarks jobs we have in our benchmarks
package (wayang-benchmark/code). Having all this running perfectly and well
documented will be a win-win situation IMO: you will get familiarised with
Wayang and you will achieve a TODO that will help us in gaining new users :)
And btw, while doing all this if you can also collect information on how we can
get the installation process simpler for non-geeky people getting Wayang
running in few steps would be absolutely great.
What do you think? Would you like to proceed with the above introductory
task/TODO?
If you are fine with it, we can create the issue for you to take care of it :)
Welcome on board!
Jorge
