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. > On 29.
