How to modify heartbeat message and its return message?
Hi,
I want to modify the heartbeat message to carry more information from worker
nodes to master node, and also want to modify the return message of
heartbeat. Do you know which file and function should I modify?
Thanks a lot,
Shen

That's for HDFS, correct?
For JobTracker -- TaskTracker heartbeats, you need to check
JobTracker.heartbeat(...) method.
It sends back a HeartBeatResponse object which is generated based on
the details recieved (TT status, etc.), which you can modify to add in
your details perhaps?
