> 1. Do not use {{String.format()}} in conjunction with SLF4J. Superfluous.
> {code:java}
> String message = String
> .format("Compute Plan for Node : %s:%d took %d ms ",
> node.getDataNodeName(), node.getDataNodePort(),
> endTime - startTime);
> LOG.info(message);{code}
> 2. Do not call an explicit toString() on an object with SLF4J parameter.
> Otherwise, the string will be created and then thrown away if the logger is
> not set to debug level. Just pass the object itself and the framework will
> call {{toString}} if needed.
> {code}
> LOG.debug("Step : {} ", nextStep.toString());
> {code}
