----------------------------------
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.
