Subject [jira] [Commented] (HDFS-10776) Revisit Hdfs Audit Logging
Date Fri, 19 Aug 2016 03:29:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15427553#comment-15427553

Allen Wittenauer commented on HDFS-10776:

FWIW, I'm writing a blog post on the origins of the audit log. I figure a lot of people would
be interested in it outside this JIRA. When it's posted, I'll add a link here.

> HDFS audit logging is considered critical in many scenarios, but it hasn't been always
implemented consistently, especially for new features. As we have seen in HDFS-9395 and the
2.7.3 release discussions in the mailing list, even bug fixes are tricky since some users
may get greatly impacted by the resulting incompatibility. The goal of this jira is to clarify
what the hdfs audit logging should do and discuss potential approaches that will allows us
to move forward.
> 1) What is the correct way of doing the hdfs audit logging? This was discussed in HDFS-9395,
but needs to be revisited as there were discussions on the fix being made with wrong assumptions. What
needs to be fixed, if HDFS-9395 is incorrect or incomplete?
> 2) What if a single standard cannot satisfy everyone? Do we need to make the audit logging
more flexible and configurable?
> 3) What is the best way of introducing future bug fixes to the hdfs audit logging that
change the output?  Some may not want a fix, while others may consider it critical and
want it asap.
