Hi,
My flume version is 1.4.0 and I have not put guava jar in classpath

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.
