Subject Initializing log4j for running RecommenderJob on AWS EMR
Date Thu, 26 Aug 2010 18:45:38 GMT

When I run the RecommenderJob on AWS EMR(Elastic MapReduce), I get the
following message in the stderr file -

log4j:WARN No appenders could be found for logger
log4j:WARN Please initialize the log4j system properly.

It will be great if someone could help me with how to initialize the log4j
system properly. On googling, I found only one useful link -

But, I still do not know where the file is? Could someone
give me a more elaborate explanation for the procedure to see the log files
or how to initialize log4j?
