Chris A. Mattmann commented on NUTCH-236: ----------------------------------------- Hi Jason, I'll have a patch prepared for this issue shortly, and I'll attach it to JIRA by this Sunday night. Thanks, Chris > PdfParser and RSSParser Log4j appender redirection > -------------------------------------------------- > > Key: NUTCH-236 > URL: http://issues.apache.org/jira/browse/NUTCH-236 > Project: Nutch > Type: Bug > Versions: 0.8-dev > Environment: Linux, Nutch embedded in an other application > Reporter: Jason Calabrese > Assignee: Chris A. Mattmann > Priority: Minor > > I just found a bug in the way the log messages from Hadoop LogFormatter are > added as a new appender to the Log4j rootLogger in the PdfParser and > RSSParser. > Since a new Log4j appender is created and added to the root logger each time > these classes are loaded log messages start getting repeated. > I'm using Nutch/Hadoop inside an other application so other may not be seeing > this problem. > I think the simple fix is as easy as setting a name for the new appender > before adding it and then at the begining of the constructor checking to see > if it's already been added. > Also as the comment says in both the PdfParser and RSSParser this code should > be moved to a common place. > I'd be happy to make these changes and submit a patch, but I wanted to know > it > the change would be welcome first. Also does anyone know a good place for > the new util method? Maybe a new static method on LogFormatter, but then the > log4j jar would need to be added to the to the common lib and the classpath. > It would also be good to create a property in nutch-site.xml that could > disable this logging appender redirection. > Like I said above I'd be more than happy to do this work, I'll just need some > guidance to follow the project's conventions. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
