Cassandra sstableloader，未还原任何数据

Question

i've been trying to use sstableloader to restore a snapshot, and while i don't have any exception when doing so, no data is restored on my new node.

here is the result of sstableloader -d newNodeIp keyspaceFolder :

Established connection to initial hosts
Opening sstables and calculating sections to stream

Summary statistics:
Connections per host : 1
Total files transferred : 0
Total bytes transferred : 0.000KiB
Total duration : 2637 ms
Average transfer rate : 0.000KiB/s
Peak transfer rate : 0.000KiB/s

i've tried running it either from the node the backup comes from or from another remote host, the result is the same.
the cassandra version is the latest stable one as of this post (3.11.1).
the source and destination keyspaces have the same name.

the folder containing the backup is structured as such:

keyspaceName/table-uuid/

^ each of these folders containing sstable files.
none of these folders contain subfolders (no backups / snapshots subfolders).
the corresponding folders on the new node are similarly named (with the exception of the uuid obviously).
should that be of interest, each node is a docker container.

any clue as to why sstableloader wouldn't be able to restore my backup please?
am i using it wrong?
don't hesitate to point out any missing info.

您还应该添加表名，而不仅是键空间。
