--------------------------------------
Summary: Clean up dead code
Key: HDFS-13330
URL: https://issues.apache.org/jira/browse/HDFS-13330
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Wei-Chiu Chuang
The follow do .. while(false) loop seems useless to me.
{code:java}
ShortCircuitReplicaInfo info = null;
do {
if (closed) {
LOG.trace("{}: can't fethchOrCreate {} because the cache is closed.",
this, key);
return null;
}
Waitable<ShortCircuitReplicaInfo> waitable = replicaInfoMap.get(key);
if (waitable != null) {
try {
info = fetch(key, waitable);
} catch (RetriableException e) {
LOG.debug("{}: retrying {}", this, e.getMessage());
}
}
} while (false);{code}
