Subject [jira] [Created] (HDFS-3535) audit logging should log denied accesses as well as permitted ones
Date Wed, 13 Jun 2012 21:49:42 GMT
Andy Isaacson created HDFS-3535:
-----------------------------------

             Summary: audit logging should log denied accesses as well as permitted ones
                 Key: HDFS-3535
                 URL: https://issues.apache.org/jira/browse/HDFS-3535
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: name-node
    Affects Versions: 2.0.0-alpha
            Reporter: Andy Isaacson
            Assignee: Andy Isaacson


FSNamesystem.java logs an audit log entry when a user successfully accesses the filesystem:

{code}
      logAuditEvent(UserGroupInformation.getLoginUser(),
                    Server.getRemoteIp(),
                    "concat", Arrays.toString(srcs), target, resultingStat);
{code}

but there is no similar log when a user attempts to access the filesystem and is denied due
to permissions.  Competing systems do provide such logging of denied access attempts; we should
too.
