MapReduce Unwinding. . . . . Map

In last discussion on MapReduce, we discussed the algorithm which is used by Hadoop for data processing using MapReduce. Now its time to understand this in detail with help of an example. Lets consider our scenario : We have 7 Node cluster where 1 Node is Name Node (NN) and rest of 6 node is Read more about MapReduce Unwinding. . . . . Map[…]

MapReduce Unwinding. . . . . .Algorithm

With discussion, in my last blog, about “How Hadoop manages Fault Tolerance” within its cluster while processing data, it is now time to discuss the algorithm which MapReduce used to process these data. It is Name Node (NN) where a user submits his request to process data and submits his data files.  As soon as NN receives data Read more about MapReduce Unwinding. . . . . .Algorithm[…]
