Subject [jira] [Created] (HDFS-3680) Allows customized audit logging in HDFS FSNamesystem
Date Wed, 18 Jul 2012 21:53:36 GMT
Marcelo Vanzin created HDFS-3680:

             Summary: Allows customized audit logging in HDFS FSNamesystem
                 Key: HDFS-3680
                 URL: https://issues.apache.org/jira/browse/HDFS-3680
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 3.0.0
            Reporter: Marcelo Vanzin
            Priority: Minor
         Attachments: accesslogger-v1.patch

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.
