Subject [jira] [Commented] (HDFS-6954) With crypto, no native lib systems are too verbose
Date Thu, 28 Aug 2014 23:57:09 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6954?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14114620#comment-14114620

Andrew Wang commented on HDFS-6954:
-----------------------------------

Hi Charles, thanks for picking this up (and thanks Allen for reporting, I was going to file
the same thing). Had a few review comments:

* I think PerformanceAdvisory would be a nice logsink to use for the CryptoCodec stuff, it
definitely relates to perf. Could do it at DEBUG level.
* Would be nice to switch PerfAdvisory to use slf4j too. If this gets too big, we can do it
in a different JIRA (or simply rename this one to be more general, i.e. "Add additional PerformanceAdvisory
logging").
