Gera Shegalov commented on MAPREDUCE-6400:
------------------------------------------
bq. We don't want to spend time reading the rest of the data, rather we just
want to abandon the transfer and move on.
Good point that we don't care about checksum verification. Initially I was only
worried about the read-ahead pool but it's not used for the shuffled data
arriving via a TCP socket.
