I am a newer for Hadoop, and am reading the code of Hadoop for a week now i am very puzzled by the relation of so many classes after i run : bin/start-all.sh
I know there are JobTrackerInstrumentation, JobTracker, Namenode etc so what is the order of their initialization? and after bin/start-all.sh and before i run any job, what exits in the system? thanks for your reply!
