Hi, I am preparing to resolve HADOOP-18207 <https://issues.apache.org/jira/browse/HADOOP-18207> ( https://github.com/apache/hadoop/pull/5717).
This change affects all modules. With this change, it will eliminate almost all the direct log4j usage. As always, landing such a big piece is tricky. I am sorry for the mishaps last time and am doing more due diligence to make it a smoother transition. I am triggering one last precommit check. Once the change is merged, Viraj and I will pay attention to any potential problems. Weichiu
