Dmytro Molkov resolved HDFS-1571.
---------------------------------
Resolution: Duplicate
Nevermind this JIRA. I did not realize it was fixed in HDFS-1087 a while back
> 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.
