@xianjingfeng I think clear unnecessary data before start shuffle server by Linux command is a better way, and clear process during shuffle server startup is a backup solution.
I prefer to improve start script to do such thing.

What's the type of disk that you use? The performance of disk is a little strange. We only delete one directory on every disk, it shouldn't take so much time.

How many files are deleted in your disk ? Uniffle has merged data in each partition, so there will not exist very large number of files. Can you do a simple test by using rm -rf？
