> If we're running Spark on a cluster, the checkpoint dir must be a non-local path. Otherwise, the attempt to read from a checkpoint will fail because the checkpoint files are written on the executors, not on the driver.
> Currently, the error message that you get looks something like the following, which is not super intuitive:
> {code}
> Checkpoint RDD 3 (0) has different number of partitions than original RDD 2 (100)
> {code}
