Navina Ramesh commented on SAMZA-693:
-------------------------------------

[~initialcontext] : I applied your patch and as you said the integration test is failing. I am not able to exactly reproduce the error you see. 

However, I see a different error that is not related to Log4J. 

{code}
testShouldStartAndRestore FAILED
    java.lang.SecurityException: class "javax.servlet.ServletRegistration$Dynamic"'s signer information does not match signer information of other classes in the same package
        at java.lang.ClassLoader.checkCerts(ClassLoader.java:895)
        at java.lang.ClassLoader.preDefineClass(ClassLoader.java:665)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:758)
        at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)
        at java.net.URLClassLoader.defineClass(URLClassLoader.java:467)
        ...
{code}

This usually happens when classes from same package are loaded from different jars and the jar file signatures don't match (perhaps??).

I can take a look at the patch once it is available for review. Please note that the integration test basically brings up a zookeeper/kafka setup and tries to run a Samza job. It is a minimum requirement for a patch to work.

> Add a simple HDFS producer and related utilities. I've been using a version of this. Initial patch comes with a very basic test and it's own subproject setup which may or may not be what we want?
> Thanks!
