Subject [jira] Created: (HADOOP-6884) Add LOG.isDebugEnabled() guard for each LOG.debug("...")
Date Tue, 27 Jul 2010 22:46:24 GMT
Add LOG.isDebugEnabled() guard for each LOG.debug("...")

                 Key: HADOOP-6884
                 URL: https://issues.apache.org/jira/browse/HADOOP-6884
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 0.22.0
            Reporter: Erik Steffl
             Fix For: 0.22.0

Each LOG.debug("...") should be executed only if LOG.isDebugEnabled() is true, in some cases
it's expensive to construct the string that is being printed to log. It's much easier to always
use LOG.isDebugEnabled() because it's easier to check (rather than in each case reason whether
it's necessary or not).
