Dear Hadoop users,
Is it possible without using java manage task assignment to implement some simple rules? Like do not launch more that 1 instance of crawling task on a machine, and do not run data intensive tasks on remote machines, and do not run computationally intensive tasks on single-core machines:etc. Now it's done by failing tasks that decided to run on a wrong machine, but I hope to find some solution on jobtracker side.. --- Dmitry
