Since `hadoop -fs ls /` seems to work on your local node, can you verify that (1) it is in fact listing the contents of CephFS, and (2) that on your worker nodes where the error is occuring that the relevant dependencies (naming the Ceph hadoop bindings) are installed and in the classpath? The error itself looks like a missing dependency, but that exception being thrown might also be tirggered by other problems while loading the bindings.
