Subject [jira] [Commented] (HIVE-9730) make sure logging is never called when not needed in perf-sensitive places
Date Tue, 24 Feb 2015 19:46:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14335313#comment-14335313

Gopal V commented on HIVE-9730:
-------------------------------

[~sershe]: Hold on, before we have checks for Log4JLogger etc, let's test with the log4j2
bridge and see if the performance issue disappears.

This is something we'll circle back to after the next profiler run.
