Mingliang Liu updated HDFS-8971: -------------------------------- Summary: Remove guards when calling LOG.debug() and LOG.trace() in client package (was: Remove guards when calling LOG.debug() and LOG.trace() in shortcircuit package) > Remove guards when calling LOG.debug() and LOG.trace() in client package > ------------------------------------------------------------------------ > > Key: HDFS-8971 > URL: https://issues.apache.org/jira/browse/HDFS-8971 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: build > Reporter: Mingliang Liu > Assignee: Mingliang Liu > > We moved the {{shortcircuit}} package from {{hadoop-hdfs}} to > {{hadoop-hdfs-client}} module in JIRA > [HDFS-8934|https://issues.apache.org/jira/browse/HDFS-8934] and > [HDFS-8951|https://issues.apache.org/jira/browse/HDFS-8951]. Meanwhile, we > also replaced the _log4j_ log with _slf4j_ logger. There were existing code > in the {{shortcircuit}} package to guard the log when calling {{LOG.debug()}} > and {{LOG.trace()}}, e.g. in {{ShortCircuitCache.java}}, we have code like > this: > {code} > 724 if (LOG.isTraceEnabled()) { > 725 LOG.trace(this + ": found waitable for " + key); > 726 } > {code} > In _slf4j_, this kind of guard is not necessary. We should clean the code by > removing the guard. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
