Hi, Its log4j actually across the board. (I think there are a couple files that have non log4j loggers? might be good to fix to log4j as well for now to be consistent)
Nonetheless, there is a JIRA for this already https://issues.apache.org/jira/browse/HUDI-233 Main thing we need to be mindful of is to ensure all the shading and everything works properly across the bundles.
