The timestamps from those logs don't correlate to the issue you pasted earlier, would it be possible to see all logs from a single instance of the issue? It would make our life much easier helping you.
In fact, I would like to see all the logs from all the datanodes plus the full output from a reducer. You could compress it and leave that on a webserver or send it to me directly. What you pasted only gives a very restricted view of what happened.
