RE: How to compile the JobTracker.java
The scheduling and resource management parts of the JobTracker have been
put in the ResourceManager.
The Map Reduce job history in the JobHistoryServer. Each MR job is managed
by its own YARN MR Application.

Thanks by answer.

Some thinks was clarified for me. I am learning about MR2, I realized that
in MR2 the JobTracker was replaced by JobHistory, is this correct?

Could you please provide more information or link about MR2?

Thank you.
