apache spark- a software which gives you great learning experience

The beauty of open source projects is that if you try to learn it , it will take you through lot of subject areas that you never heard about. Apache Spark is one of them for me. I started hearing about it when I started to follow big data&hadoop. Ok,I thought , let me install it in my ubuntu machine . I found that it is quite easy and the interesting part is that it took me through interesting subjects like ML(machine learning), Streaming,functional programming (scala) etc..
