Subject [jira] Created: (HDFS-1320) Add LOG.isDebugEnabled() guard for each LOG.debug("...")
Date Mon, 26 Jul 2010 23:07:16 GMT
Add LOG.isDebugEnabled() guard for each LOG.debug("...")
--------------------------------------------------------

                 Key: HDFS-1320
                 URL: https://issues.apache.org/jira/browse/HDFS-1320
             Project: Hadoop HDFS
          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 wheather
it's neccessary or not).
