Subject [jira] [Commented] (HDFS-3680) Allow customized audit logging in HDFS FSNamesystem
Date Fri, 30 Nov 2012 19:23:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13507576#comment-13507576

Aaron T. Myers commented on HDFS-3680:

I've just reverted the trunk commit, but you'll still probably see some Hudson integration
comments here. Please just ignore them.

Suresh - thanks for taking another look. I think that Marcelo's investigation has probably
addressed all of the concerns you've raised previously, but it will be good to hear your thoughts.

> Currently, FSNamesystem writes audit logs to a logger; that makes it easy to get audit
logs in some log file. But it makes it kinda tricky to store audit logs in any other way (let's
say a database), because it would require the code to implement a log appender (and thus know
what logging system is actually being used underneath the fa├žade), and parse the textual
log message generated by FSNamesystem.
> I'm attaching a patch that introduces a cleaner interface for this use case.
