> We are using nutch for high volume crawls. We noticed that FetcherJob ReduceTask fetches
some websites multiple times for long lasting queues. I have discovered the reason of this
is mapred.reduce.tasks.speculative.execution settings in hadoop. 1.x has speculative execution
turned off. I create a patch for 2.x
