How to use s3 (s3 native) as input / output for hadoop MapReduce job. In this tutorial we will first try to understand what is s3, difference between s3 and s3n and how to set s3n as Input and output for hadoop map reduce job. Configuring s3n as I/O may be useful for local map reduce jobs (ie MR run on local cluster), But It has significant importance when we run elastic map reduce job (ie when we run job on cloud). When we run job on cloud we need to specify storage location for input as…Continue

There is little time, about 3 or 4 years, if you wanted to process a large amount of textual data or web logs, you need to mobilize large servers and implement consistent SQL programs, long to be developed long and long to give results. Fortunately requests were few and generally volumes were measured at most in terabytes. Now e-commerce and social media have been largely developed, and many companies see their customer relationships, and therefore their survival, entirely dependent on the…Continue
