> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: build
> Reporter: Mingliang Liu
> Assignee: Mingliang Liu
> Fix For: 2.8.0

> 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], and
> {{BlockReader}} in
> [HDFS-8925|https://issues.apache.org/jira/browse/HDFS-8925]. Meanwhile, we
> also replaced the _log4j_ log with _slf4j_ logger. There were existing code
> in the client package to guard the log when calling {{LOG.debug()}} and
> {{LOG.trace()}}, e.g. in {{ShortCircuitCache.java}}, we have code like this:
> {code:title=Trace with guards|borderStyle=solid}
> 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 from the client package.
> {code:title=Trace without guards|borderStyle=solid}
> 724 LOG.trace("{}: found waitable for {}", this, key);
> {code}
