[jira] Created: (HADOOP-6884) Add LOG.isDebugEnabled() guard for
each LOG.debug("...")
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).
