Amar Kamat updated HADOOP-2801:
-------------------------------

    Description: I ran into a situation where the non-speculative task and the 
speculative task were started at the same time. Ideally there should be a 1 min 
gap for speculation. One possible reason would be the usage of {{startTime}} in 
deciding whether there is a speculative lag.  (was: I ran into a situation 
where the non-speculative task and the speculative task were started at the 
same time. Ideally there should be a 1 min gap for speculation. One possible 
reason would be the usage of {{startTime}}in deciding whether there is a 
speculative lag.)
