To filter spam, various techniques are used. Techniqueslike Nave Bayesian Classifier, Support Vector Machine (SVM) etc. are often used. Also, a number of tools for spamfiltering either paid or free are available. Amongst all techniques SVM is mostly used. SVM is computationally intensiveand for...

In MapReduce, the job completion time is based on the slowest running task. This type of task is known as straggler. This paper reviews the types of data skew and several skew mitigating techniques to solve the issue.S.DhanalakshmiB.ArputhamaryDr. L. Arockiam...
These three techniques suffers some problem. Those problems are addressed in this paper. Slot allocation has the problem of allocating the slots for the task when there is no free map and reduce slots are not available this can be solved by establishing the communication between two cluster. ...
To provide security and authentication to the data, many algorithms and techniques were evolved, in which the cryptographic techniques remains best. For the encryption process, Images were considered as the best source to maintain security. The usage of image is good solution for providing better ...
So, dynamic optimization techniques for such join intensive tasks on MapReduce need to be investigated. Scalable RDF based data can be retrieved as per requirement it is more time consuming. To improve query execution process on RDF using MapReduce is key technique. Proposed system gets RDF data...
The techniques I am using here are Data Cleaning in Hadoop, Push Model and caching. These three methods will help in providing efficient work on Hadoop. It will save a lot of time while working on the large data sets. The already implemented Map-Reduce Framework [11] is being modified so...
