java.io.IOException: alluxio.exception.DirectoryNotEmptyException

[vinayak gadag]

Getting the below error whenever I'm trying to delete file from alluxio storage.

Caused by: java.io.IOException: alluxio.exception.DirectoryNotEmptyException Cannot delete the directory /abc/xyz because the UFS has contents not loaded into Alluxio. Sync Alluxio with UFS or run delete with unchecked flag to forcibly delete.

My Questions are .!

1. What will be the proper solution for this?
2. When do we get this error?
3. How can we reproduce this? - I'm not able reproduce this consistently.

Thanks,
Vinayak

Adding alluxio version and UFS information

Alluxio version- 1.5.0
UFS - HDFS

Hi Vinayak,

Which UFS are you using?.

- The error message is expected behavior when you attempt to delete a file/directory from Alluxio when its contents (including sub-directories/files) are not loaded into Alluxio previously.

- You can turn this feature off using the parameter alluxio.user.file.delete.unchecked=true

To reproduce this create a directory in the UFS (not through Alluxio) with a file in it. Then attempt to delete the directory in Alluxio w/o listing its contents first.

Let me 

Thanks,

Adit

Hey thanks for the reply Adit, we are using HDFS as underFS system and currently I have set unchecked flag to true and not faced any issues till now.

Thanks for the reproducing steps.

- Vinayak,
