Sorry. This mostly won't work... we have significant changes in the interface between the JobTracker and schedulers (FS/CS) b/w 20.2 and 20.203 (performance, better limits etc.).
Your best bet might be to provision Hadoop yourself on EC2 with 0.20.203+. Good luck! Arun On Oct 26, 2011, at 2:55 PM, Kai Ju Liu wrote: > Hi.
