[jira] [Created] (HDFS-12746) DataNode Audit Logger

Erik Krogen created HDFS-12746:
----------------------------------

             Summary: DataNode Audit Logger
                 Key: HDFS-12746
                 URL: https://issues.apache.org/jira/browse/HDFS-12746
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode, logging
            Reporter: Erik Krogen


I would like to discuss adding in an audit logger for the Datanodes. We have audit logging on pretty much all other components: Namenode, ResourceManager, NodeManager. It seems the DN should have a similar concept to log, at minimum, all block reads/writes. I think all of the interesting information does already appear in the DN logs at INFO level but it would be nice to have a specific audit class that this gets logged through, a la {{RMAuditLogger}} and {{NMAuditLogger}}, to enable special handling.
