             Summary: Spark example code potentially confusing
                 Key: IGNITE-10647
                 URL: https://issues.apache.org/jira/browse/IGNITE-10647
             Project: Ignite
          Issue Type: Improvement
    Affects Versions: 2.7
            Reporter: Stephen Darlington
            Assignee: Stephen Darlington


This started with a [question on Stack Overflow|https://stackoverflow.com/questions/53704478/apache-ignite-spark-dataframes-client-vs-server-doubts/53704993#53704993]. In short, the user copy-and-pasted the whole sample code over, without realising that in addition to firing up a Spark client it also runs an Ignite server.

The advantage of this is obviously that the code is entirely self-contained.

However, there's little to suggest what's going on in the code, which bits are just setting stuff up and which bits are actually demonstrating the Spark integration.

Maybe there's a way to restructure it to make it clearer? Or a few extra comments?
