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.

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.

To increase the heap size, rename the file  flume-env.sh.template  to flume-env.sh in conf directory and uncomment the JAVA_OPTS line and edit the minimum and maximum heap. Example: JAVA_OPTS="-Xms512m -Xmx1024m"
