Hi,, I am new here so I am sorry if it is not the right place for my question. I want to edit in hadoop source code So I can record information "in txt file"about each executed task in hadoop mapreduce cluster. Information will be like: job name, task name, input records and so on... and I want to record this info before the job finishes just after the task will finish execution.
I opened the source code but I didn't know which class will be related to my issue? thanks so much ...
