I think I am almost lost in the internals of Spark
I am a bit new to Spark, except that I tried simple things like word count, and the examples given in the spark sql programming guide.
Now, I am investigating the internals of Spark, but I think I am almost lost, because I could not grasp a whole picture what spark does when it executes the word count.
Is there detailed guide into the intervals about what spark does when it execute the word count?Thanks. There is a lot of good explanation about the process how Hadoop does the word count.

Thank you, Tobias. I will look into the Spark paper. But it looks that the paper has been moved, http://www.cs.berkeley.edu/~matei/papers/2012/nsdi_spark.pdf.
A web page is returned (Resource not found)when I access it.
