Ceph » CephFS

The "get" command in cephfs-shell when used to get a file that doesn't exist on ceph filesystem, would throw an error but still would create a directory in the local filesystem:

CephFS:~/>>> get foo /home/dparmar/foo
opendir failed at foo: No such file or directory [Errno 2]

Upon doing "ls" in local filesystem:

[dparmar@fedora ~]$ ls
ceph-prs-repo  demo     Documents  file1  Music     Public      quickceph     sepia-vpn-client.tar.gz  ticket_wfh
cephrunrepo    Desktop  Downloads  foo    Pictures  pycharm.sh  rh_resources  Templates                Videos

It creates directory /home/dparmar/foo/foo which is basically empty.

Solution: There's a block of code in do_get() that upon finding ZERO files, does

os.makedirs(root_dst_dir + b'/' + root_src_dir)

which basically would create this kind of directories. This code can be eliminated and instead directly thrown an error something like "file doesn't exist" and return.
