sam commented on SPARK-4492:
----------------------------
Well I do try to package Spark in my jar (had to fight an epic deduplicate
battle with sbt), it's the only way I can get syntax highlighting for Spark
stuff to work in Intellij (rather than using "provided"). Why is Spark so
special? I've used a lot of client libraries and I have not needed to use some
special script to execute jars. Historically I've just built a fat jar,
deploy, run with java -cp.
What exactly does spark-submit do? The documentation says it sets up the
classpath, is that it?
I can get it working with spark-submit, but it just doesn't feel right to me
using a script to execute a jar. What happens when new shiny tool X comes out,
and new shiny tool X is also a nightmare to build, so the authors decide to
solve the problem by writing a script to execute the jar called run-X-jar ...
then I won't be able to use both X and Spark.
