Hi,

The central class is FSNamesystem.java downwards. I'd advise drilling
down from the NameNodeRpcServer sources at
https://github.com/apache/hadoop-common/blob/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/NameNodeRpcServer.java,
for any client operation your curiosity wants to dive into.
