Algorithm 3 shows the details
of the locality-aware scheduling algorithm. The scheduler not
only calculates the weight of data interference to avoid rare resource
allocated in an easy way but also introduces the concept of weight of
data interference to enhance the data locality in the MapReduce
framework. The locality-aware scheduler thus reduces the overhead
of data transmission, which is caused by the network delay, and the
performance of cloud platform also is improved by the localityaware
scheduler.
