You would suggest: https://github.com/ottogroup/flink-spector for unit
tests?

Thanks, this sounds like a good idea - can you recommend such a project?

If you want to really learn then I recommend you to start with a flink project 
that contains unit tests and integration tests (maybe augmented with 
https://wiki.apache.org/hadoop/HowToDevelopUnitTests to simulate a HDFS cluster 
during unit tests). It should also include coverage reporting. These aspects 
are equally crucial to know for developers to develop high quality big data 
applications and virtually all companies will require that you know these 
things. 

I am not sure if a hello world project in Flink exists containing all these but 
it would be a good learning task to create such a thing.

getting started with link / scala

[Georg Heiler]

Getting started with Flink / scala, I wonder whether the scala base library
should be excluded as a best practice:
https://github.com/tillrohrmann/flink-project/blob/master/build.sbt#L32
// exclude Scala library from assembly
assemblyOption in assembly := (assemblyOption in
assembly).value.copy(includeScala = false)

Also I would like to know if https://github.com/tillrohrmann/flink-project is
the most up to date getting started with flink-scala sample project you
would recommend.

Best,
Georg
