Checkpoints in Spark

I'm curious about what kind of things are saved in the checkpoints.

I just changed the number of executors when I execute Spark and it didn't
happen until I remove the checkpoint, I guess that if I'm using
log4j.properties and I want to changed I have to remove the checkpoint as
well.

When you need to change your code and don't wan to to lose any data, Is
there any easy way to do this change in the code?
