 Review comment:
   When I run accumulo test I usually add a line like the following to `log4j-service.properties`
   
   ```
   log4j.logger.org.apache.accumulo=DEBUG
   ```
   
   This only enables debug logging for Accumulo code.  The change `log4j.rootLogger=DEBUG, file` will enable debug logging for everything like Hadoop and Zookeeper.  I am not sure how voluminous or useful this is.
