Andrew Or 2e2f32603c [SPARK-8581] [SPARK-8584] Simplify checkpointing code + better error message
This patch rewrites the old checkpointing code in a way that is easier to understand. It also adds a guard against an invalid specification of checkpoint directory to provide a clearer error message. Most of the changes here are relatively minor.
