Hi All, I've a question about Heartbeat implementation in Hadoop. I'm working on dependability evaluation of Hadoop, I'm interested to find all the code snippets which implements the heartbeat. Right now I've found one place
1- heartbeat with piggybacking is used by (JobTracker.java and TaskTracker.java)in Hadoop to check the health status of each task. Do you know any package/class that implements the heartbeat? I really appreciate your feedback. Mehdi PS.Here I've found these classes so far, does anyone knows if this list is complete? mapreduce\src\java\org\apache\hadoop\mapred\TaskTracker.java mapreduce\src\java\org\apache\hadoop\mapreduce\server\tasktracker\TTConfig.java mapreduce\src\contrib\mumak\src\java\org\apache\hadoop\mapred\SimulatorTaskTracker.java mapreduce\src\contrib\mumak\src\java\org\apache\hadoop\mapred\SimulatorEngine.java mapreduce\src\java\org\apache\hadoop\mapred\JobTracker.java mapreduce\src\java\org\apache\hadoop\mapred\TaskTrackerManager.java mapreduce\src\java\org\apache\hadoop\mapreduce\server\jobtracker\JTConfig.java mapreduce\src\contrib\mumak\src\java\org\apache\hadoop\mapred\SimulatorJobTracker.java mapreduce\src\java\org\apache\hadoop\mapred\InterTrackerProtocol.java mapreduce\src\java\org\apache\hadoop\mapreduce\util\ConfigUtil.java
