I couldn't reproduce the issue,
I run sftp: docker run -v
/home/claudio/tmp/lixo/random_files:/home/foo/upload -p 2222:22 -d
atmoz/sftp foo:pass
consumer endpoint like this with your parameters
from("sftp:localhost:2222/upload/mysub1/mysub2/mysub3?username=foo&password=pass"
debug log shows:
Auto creating directory: upload/mysub1/mysub2/mysub3
$ ls -lR
.:
total 4
drwxrws---. 3 claudio users 4096 Sep 22 16:33 mysub1
./mysub1:
total 4
drwxrws---. 3 claudio users 4096 Sep 22 16:33 mysub2
./mysub1/mysub2:
total 4
drwxrws---. 2 claudio users 4096 Sep 22 16:36 mysub3
Some research indicates some configuration or bug in the sftp server.
