Daryn Sharp updated HDFS-11641:
-------------------------------
Attachment: HDFS-11641.patch
Very simple patch to change to swap HdfsFileStatus to FileStatus.
FSN#startFile is the only operation that still passes HdfsFileStatus since it
already computed it for the client.
> Reduce cost of audit logging by using FileStatus instead of HdfsFileStatus

> URL: https://issues.apache.org/jira/browse/HDFS-11641
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs
> Affects Versions: 2.0.0-alpha

>
> Audit logging operations create a HdfsFileStatus but audit logging promptly
> converts it to a FileStatus to pass to the loggers. A HdfsFileStatus is more
> expensive to create, ex. multiple node to root scans for feature info that
> will only be discarded in the conversion to FileStatus. Operations should
> create a FileStatus to eliminate all the superfluous overhead.
