Optimization and data locality in mapreduce
WebThe various categories in Hadoop Data Locality are as follows: 1. Data local data locality in Hadoop. In this, data is located on the same node as the mapper working on the data. In this, the proximity of data is very near to computation. Data local data locality is the most preferred scenario. 2. Intra-Rack data locality in Hadoop WebThe particle swarm optimization (PSO) algorithm has been widely used in various optimization problems. Although PSO has been successful in many fields, solving optimization problems in big data applications often requires processing of massive amounts of data, which cannot be handled by traditional PSO on a single machine. There …
