Zuo Dao updated SPARK-32172:
----------------------------
Description:
Use Files.createDirectory() to create local directory instead of File.mkdir()
in DiskBlockManager.
Many times, we will see such error log information like "Failed to create local
dir in xxxxxx". But there is no clear information indicating why the directory
creation failed.
When Files.createDirectory() fails to create a local directory, it can give
specific error information for subsequent troubleshooting(also throws
IOException).
