-----------------------------------------
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.
> Revisit Hdfs Audit Logging
> --------------------------
>
> Key: HDFS-10776
> URL: https://issues.apache.org/jira/browse/HDFS-10776
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.7.2
> Reporter: Kuhu Shukla
> Assignee: Kuhu Shukla
>
> 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.
