The setQuietMode method in Configuration (and inherited by JobConf) is used only to set the logging level of the Configuration class. If you set it, then any errors while loading the Configuration will be printed out. This variable has nothing to with the logging level of your map-reduce job.

I looked at the JobConf interface and found setQuietMode(), which seemed like it would set the debug level high (though how high isn't clear). Is there a way to explicitly set it to info, or debug?
