-------------------------------------------------------------------
Let me rephrase. It might be a compat issue given the class we're trying to
find is CorruptionException, which would be surprising because org.iq80.snappy
is supposed to be a drop in replacement for org.xerial.snappy. But it is
definitely a classpath issue on the server because the reported error is
NoClassDefFoundError out of a coprocessor exec.
