Description

https://github.com/apache/hadoop/blob/178751ed8c9d47038acf8616c226f1f52e884feb/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/lib/input/CombineFileInputFormat.java#L428-L429

 

LOG.info("DEBUG: Terminated node allocation with : CompletedNodes: "
+ completedNodes.size() + ", size left: " + totalLength);

1. Use SLF4J Parameterized logging
2. The message literal string contains the word "DEBUG" but this is INFO level logging. Remove the word "DEBUG" and set the logging level to DEBUG
