Re: Cannot find JobTracker and TaskTracker classes in Hadoop 2.0.2-alpha
Hi Thoihen

Hadoop 2.x (and 0.23.x) releases have MapReduce running on YARN, which
operates on the ResourceManager/NodeManager architecture  and not
JobTracker/TaskTracker. Hadoop 1.x releases have the JT/TT architecture if
you are interested in that.

Thanks
Karthik
