This looks like a bug, which I'll fixup today. But it shouldn't be
related to the problems you are seeing.

This looks like you don't have the CephFS Java bindings in a place
that Hadoop can locate. Typically you can stick the libcephfs-jar file
into the lib directory of Hadoop, or add it to your classpath.
