samza-log4j/src/main/java/org/apache/samza/logging/log4j/StreamAppender.java 
(line 176)
<https://reviews.apache.org/r/44418/#comment187903>

    jobModelRef is an AtomicReference. Initial value is null, unless the 
JobCoordinator is instantiated. can you add a test to verify that this will not 
result in an NPE?
    
    Also, it will be useful to run hello-samza with StreamAppender and verify 
that the functionality is not broken.
