When the JobTracker distributes workload/computation to the servers that are storing data it tries to put the workload on the server co- located with the data to be mined. If that server is already being utilized then it sends the computation to another server in the same cabinet as the ...
Hadoop is an open-source framework that allows to store and process big data in a distributed environment across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. ...
