> By default, Flink creates subdirectories named by UUID (job id) under
> checkpoint directory for each job. It's a good means to avoid collision.
> However, it also bring in some effort to remember/find the right directory
> when recovering from previous checkpoint. According to previous discussion

> subdirectories under the checkpoint directory. For compatibility
> considerations, we create the subdirectories by default.
