i have hadoop cluster (version 1.0.3) , analyses. reasons, map task can decide, weather reasonable run through data on specific node. if it's yes, job run scientific analyses. if not, nice reschedule map task attempt on different node. can predict node reasonable restart of map task. don't want use skipping feature, since data not bad , shouldn't skipped. appropriate, if specific data processed again @ end of map phase.
do have suggestions?
greetings
