Subject [jira] [Created] (HDFS-11641) Reduce cost of audit logging by using FileStatus instead of HdfsFileStatus
Date Tue, 11 Apr 2017 17:20:41 GMT
Daryn Sharp created HDFS-11641:
----------------------------------

             Summary: Reduce cost of audit logging by using FileStatus instead of HdfsFileStatus
                 Key: HDFS-11641
                 URL: https://issues.apache.org/jira/browse/HDFS-11641
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
    Affects Versions: 2.0.0-alpha
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


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.
