SAS and Hadoop work together. Coexistence is not a pipe dream; it's here now. SAS goes to the data in Hadoop. It's a two-way relationship: SAS makes calls to Hadoop/OSS and Hadoop/OSS calls back. Hadoop is evolving (with rapidly revolving poster children) -and SAS is evolving with it. Use the best tool for the job.

white paper outlines five key questions to ask before adopting a Hadoop distribution, with an eye toward preventing buyer's remorse. 1 What does it take to make Hadoop . Hadoop is lacking in another vital area: security. As one blogger put it, Hadoop is a hacker honeypot. As we put more data into Hadoop, security must increase.

Hadoop uses a hard-coded execution pipeline. No operator-model is used. However Hadoop's query execution strategy may be ex-pressed as a physical operator DAG. To our knowledge, this paper is the first to do so in that detail and we term it The Hadoop Plan. Based on this we then reason on The Hadoop Plan. 2.1 The Hadoop Plan
Hadoop Common: It is a set of common utilities and libraries which handle other Hadoop modules. It makes sure that the hardware failures are managed by Hadoop cluster automatically. Hadoop YARN: It allocates resources which in turn allow different users to execute various applications without worrying about the increased workloads.

As Hadoop MapReduce became popular, the number and scale of MapReduce programs became increasingly large. To utilize Hadoop MapReduce, users need a Hadoop plat-form which runs on a dedicated environment like a cluster or cloud. In this paper, we construct a novel Hadoop platform, Hadoop on the Grid (HOG), based on the OSG [6] which
