Subject [jira] Created: (HDFS-1571) Improve performance of audit log
Date Thu, 06 Jan 2011 03:13:46 GMT
Improve performance of audit log
--------------------------------

                 Key: HDFS-1571
                 URL: https://issues.apache.org/jira/browse/HDFS-1571
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Dmytro Molkov


We currently use java Formatter for audit log formatting. I've done some experiments with
it versus simply creating a string of the same format using StringBuilder and apparently if
we were to use StringBuilder we can make audit log function 5-10x faster.
Since it is a useful feature and the namenode under heavy load logs a lot this performance
improvement is worth it.
