That's not necessarily a bad thing. Hadoop (not Giraph) has native
code library it can use for improved performance. You'll see this
message when running on a cluster that's not been deployed to use the
native libraries. If I follow what you wrote, most likely your work
project cluster is so configured. Unless you actively expect to have
the native libraries loaded, I wouldn't be concerned.
