Write a short note on the disadvantages of Mapreduce?
Submitted by: AdministratorSome of the shortcomings of mapreduce are:
One-input two-phase data flow is rigid i.e. it does not allow for multiple step processing of records.
Being based on a procedural programming model this framework requires code for simple operations.
The map and reduce functions being opaque does not allow for optimization easily.
