Abstract
In cloud computing, data is moved to a remotely
located cloud server. Cloud server faithfully
stores the data and return back to the owner
whenever needed. Data and computation
integrity and security are major concerns for
users of cloud computing facilities. Today's
clouds typically place centralized, universal
trust in all the cloud's nodes.Hadoop is founded
on MapReduce, which is among the most
popular programming items for huge knowledge
analysis in a parallel computing environment. In
this paper, we reward a particular efficiency
analysis, characterization, and evaluation of
Hadoop MapReduce WordCount utility.
