Erik Steffl updated HDFS-1320: ------------------------------ Attachment: HDFS-1320-0.22-2.patch > 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 > > Attachments: HDFS-1320-0.22-1.patch, HDFS-1320-0.22-2.patch, > HDFS-1320-0.22.patch > > > 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). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
