> MRAppMaster uses {{TaskAttemptImpl::resolveHosts}} to determine the dataLocalHosts for each task when the location of data split is IP, which will call a lot of times ( taskNum * dfsReplication) of function {{InetAddress::getByName}} and most of the funcition calls are redundant. When the job has a great number of tasks and the speed of DNS resolution is not fast enough, it will take a lot of time at this stage before the job running.
