I ran the example app with the command line below
yarn jar twill-examples-yarn-0.3.0-incubating-SNAPSHOT.jar
org.apache.twill.example.yarn.HelloWorld zk1:2181,zk2:2181,zk3:2181
The yarn has its own classpath, that include a guava with version 11.0.2.
Twill example build a fat jar with guava 13.0.1 inside. But seems the
classloader chose the older one. There is a collision.
How do you guys solve this kind of problem? Did you have came across that
when you running the yarn example?
Thanks,
