Guava should be already present in Flume lib directory. I downloaded and verified it. You
should have guava-10.0.1.jar in Flume lib directory.

Can you try with a fresh Flume download? IMHO, it should work, then try to debug the broken
env.

HTH!

Looks like you are running with a guava version that's different than the one that was used
to compile. Flume uses guava 11.0.2 per flume/pom.xml.
