Subject [jira] [Commented] (HIVE-9750) LLAP: avoid log locks in operators
Date Mon, 23 Feb 2015 08:44:11 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14333108#comment-14333108

Gopal V commented on HIVE-9750:
-------------------------------

isLogDebugEnabled is going the right way.

For the INFO logging, we'll need to use the log4j-jcl 2.x upgrade-path to get throughput friendly
logging.

> Basically wrap all LOG.xx calls in isLogXXXEnabled to avoid unnecessary locks on these
calls.
