I received the following error after upgrading from 0.10.0 to 0.11.0. I
understand the underlying issue, but I am not finding the exact cause. No other
jar contains ServletRegistration except for
avax.servlet-3.0.0.v201112011016.jar which is a dependency of samza-core.
Hadoop has a dependency on older servlet and jetty jars. Would love to upgrade
everything, but many of the transitive dependencies are quite old.
I have seen this error in the mailing list (triggered by an integration test),
but there was no resolve. Hoping someone has encountered and fixed this issue.
