I've a question about Heartbeat implementation in Hadoop-HDFS. I'm interested to find and modify the code snippets which implements the heartbeat. Right now I've found two main classes
HeartBeat is used by DataNode.Java (Heartbeat sender) and NameNode.java (Heartbeat reciever) for fault detection purpose. Can anyone confirm that I found the right classes (I mean the core classes) Thanks MM Here I've the details of Files or packages that I could find: hdfs\src\java\org\apache\hadoop\hdfs\server\blockmanagement\DatanodeManager.java hdfs\src\java\org\apache\hadoop\hdfs\server\namenode\NameNode.java hdfs\src\java\org\apache\hadoop\hdfs\server\namenode\FSNamesystem.java hdfs\src\java\org\apache\hadoop\hdfs\server\datanode\DataNode.java hdfs\src\java\org\apache\hadoop\hdfs\server\protocol\DatanodeProtocol.java
