Revert [SPARK-39204](https://issues.apache.org/jira/browse/SPARK-39204) to break the call from `o.a.spark.util.Utils#createTempDir` to `JavaUtils#createTempDir`, then all other calls of `JavaUtils#createTempDir()` only exist in test case. 3. https://github.com/apache/spark/pull/40598 try to restore `Utils#createTempDir` use `ShutdownHookManager#registerShutdownDeleteDir` to cleanup `tempDir` also cc @HyukjinKwon WDYT? -- This is an automated message from the Apache Git Service.
