[SPARK-25818][CORE] WorkDirCleanup should only remove the directory at the beginning of t⦠## What changes were proposed in this pull request? The cleanup mechanism will clear all the eligible directories under SPARK_WORK_DIR. If the other configured paths are the same as the SPARK_WORK_DIR configuration, this will cause the file directories of other configuration items to be deleted by mistake. For example, the SPARK_LOCAL_DIRS and SPARK_WORK_DIR settings are the same.
