Description

Similar to the fix for AVRO-115. In file:

hadoop-rel-release-2.7.2/hadoop-hdfs-project/hadoop-hdfs-nfs/src/main/java/org/apache/hadoop/hdfs/nfs/nfs3/OpenFileCtxCache.java

in line 72, the logging code:

LOG.trace("openFileMap size:" + openFileMap.size());

In the same class, there is a method in line 189:

  int size() {
    return openFileMap.size();
  }

We can tell that openFileMap.size() could be replaced by method size() for the case of readability and simplicity
