Hi, I'm currently working on NUTCH-303 so that nutch uses commons logging facade API and log4j as the default implementation. All the code is actually switched to and uses Commons Logging API, and I have replaced some System.out and printStackTrace to make use of Commons Logging.
To finalize this patch, my problem is on the configuration: 1. Does the back-end and front-end should have the same logging configuration? 2. What kind of configuration do you think is the best one by default? For now, I have used the same log4 properties than hadoop (see http://svn.apache.org/viewvc/lucene/hadoop/trunk/conf/log4j.properties?view=markup&pathrev=411254 ) for the back-end, and I was thinking to use the stdout for front-end. What do you think about this? 3. When using the default DRFA appender (Daily Rolling File Appender) in nutch, should I log in the the hadoop log file or in a nutch file? Thanks for your feed-back.
